generation of automation technologies and Emerson is the clear 

choice to move your business forward for decades to come. 

Aging I/A Series systems need to be modernized and Emerson 

is committed to making your transition to a DeltaV™ system, 

smooth, low risk and cost effective. From early modernization 

planning to long term lifecycle care, Emerson has provided 

industry leading solutions and service to complete more than 

130 projects replacing Foxboro I/A Series systems. Partner with 

us for your transformation to a digital architecture, resulting in 

improved business performance and competitive edge.

Why Choose Emerson As Your 

Automation Partner?

Modernization projects are different. They require knowledge 

of both old and new technology and have fewer degrees of 

freedom than greenfield projects, i.e. space, time, and budget. 

The transition project will impact operations, often must be 

done during short shutdown windows and has the potential  

to put production at risk.

This puts a premium on risk reduction, flexibility,  

and capital efficiency.

OVERVIEW

The I/A Series system DCS Fieldbus Modules (FBMs) 

are for migration of APACS+™ automation systems 

manufactured by Siemens® Energy & Automation, 

Inc. and Moore Products Co. The FBMs plug directly 

into an existing electronic nest to replace process 

input and output modules.

The I/A Series system DCS FBM family provides a 

migration path from APACS+ process I/O 

components to I/A Series display and supervisory 

functions. No additional communication devices are 

required. No multi-vendor communication software 

licensing is required.

The I/A Series system DCS FBM family replaces the 

APACS+ I/O modules. Once integrated, the process 

is controlled entirely by the advanced I/A Series 

algorithm set.

The I/A Series system DCS FBM product includes 

connectors to enable integration of original process 

signals to I/A Series systems while keeping the field 

interface and wiring. It provides access to all process 

signals connected to the APACS+ system by 

providing the connection between the Field 

Termination Assemblies (FTAs) and the I/A Series 

system. All process signals become fully integrated 

into the I/A Series system through the use of process 

data for operator display, history, alarming and 

control.

Operator functions and engineering configuration are 

accomplished by the I/A Series system at any 

I/A Series operator workstation. Because all process 

values become part of the I/A Series system, all 

configuration data is maintained by the system as 

native I/A Series configurations.

This migration path provides plant operations with all 

the power and flexibility of the I/A Series system.

FUNDAMENTAL PRINCIPLE

Invensys believes that it is only acceptable to 

interface with competing manufacturers’ operating 

systems in two ways:

 Through high level public gateways

 At the lowest level directly to field devices without 

communicating with proprietary buses or 

components.

The Invensys migration product offerings adhere to 

this principle.

I/A Series® system Field Control Processor 270 (FCP270)

modules mounted on a baseplate and distributed control

system (DCS) Fieldbus Modules replace the APACS+ Control

and I/O modules and connect existing field devices to the I/A

Series system via a 2 Mbps HDLC Fieldbus and high-speed

Ethernet network

Ingress Protection

The metal enclosures provide the outer layer of protection for the control electronics.

Other layers are provided by the module covers and built into the modules. This

approach to protection means that a minimum of contaminants in the plant

environment reaches the control components, thus greatly extending the life of the

equipment.

For sealed, non-adjoined G61 enclosures, heat is transferred from the interior

surfaces of the enclosure and then dissipated by the enclosure’s exterior surfaces into

the plant environment. Air is not exchanged between the enclosure’s interior and the

outside environment. Therefore, contaminants are minimized inside the enclosure.

The enclosures support convenient top or bottom cable entry for TA cabling and

power wiring. Vented enclosures with roof-mounted fans are not recommended with

top cable entry, due to the location of the power supplies.

Features

• Uptoseven1.800 mm(70.8 in) vertical DIN rails for mounting of termination

assemblies (TAs) and terminal blocks for marshalling, to provide a total of 12.6 m

(41.3 ft) of linear rail space

• Ventedorsealed enclosure selection for use in ordinary (IP 43/55) or harsh (IP

55/66) rated environments

• EMCcompliantversion available — vented (IP43/55) with roof-mounted fans

• Option for redundant 480 W (P0923VD) or 960 W 24 V DCfield power supplies

• Mainpowerentry includes disconnect terminal blocks, or 10A, Type D, double

pole circuit breakers

• Optional EMC/RFI line filters for redundant main power (Triconex recommended)

• Alarmcontact terminal block assembly for door intrusion monitoring switches,

enclosure temperature switch, and field power supply status

• Optional door intrusion monitoring

• Bottomcable entry for standard power wiring and cables for Triconex termination

devices, such as External Termination Panels (ETPs), Field Terminations, and

External Termination Assemblies (ETAs)

NOTE: Duetothe placement of field power supplies, top entry is not

recommended for this enclosure.

• Available PVC or non-PVC wireways for field I/O cabling, with optional signal

segregation barrier plate

• Generous76mmx102mm(3inx4in)wireductswith adequate capacity for

Overview

The G61EcoStruxure™ Triconex™ Tricon termination enclosure is specifically

designed for housing Triconex termination devices and additional customer-supplied

terminal blocks for marshalling. This enclosure may accommodate the termination of

Tricon modules which are housed in a G60 Tricon System Enclosure or G62/G72

Tricon System and Termination Enclosure.

The G61enclosure is available as a vented or sealed enclosure. It can be configured

with:

• Uptosevenvertical DIN rails for mounting of Triconex termination devices and

additional customer-supplied terminal blocks for marshalling

• Redundantpowersupplies (480 W or 960 W 24 VDCpower supplies) for field

power

The G61vented enclosure is a free-standing, floor mounted unit with an IP43/55

rating for location in mild (ordinary) environmental areas.

The G61sealed enclosure is a free-standing, floor mounted unit, with options for

either an IP55 or IP66 rating for location in harsh environments.

Sealed enclosures with an IP66 rating provide a higher level of protection from

airborne contamination.

NOTE: In regions that require EMC compliance, you must order the EMC

compliance option if the Triconex termination devices for Tricon modules SMM or

SRXMwill be installed in this enclosure. Without these termination devices, the

enclosure already fulfills the requirements for EMC compliance.

An optional door intrusion monitoring switch is available for each door on this

enclosure. Each switch is prewired to a set of alarm status terminal blocks.

The G61enclosure can be installed bayed or adjoined to other Triconex enclosures to

maximize the use of floor space and ease of cabling. The enclosures can be bayed

together using third-party kits.

This enclosure and its configurations have been tested and qualified by Foxboro for

use with the Tricon equipment.

INTRODUCTION

The G60 enclosure is specifically designed for

housing Tricon system chassis and modules. It is

designed for use with the G61 or G66 Tricon

Termination Enclosures, and is available as a vented

enclosure only.

The G60 enclosure can be configured with up to

three Tricon chassis. Main power entry can include

optional EMC/RFI line filters. It is a free-standing,

floor mounted unit with an IP 43 rating for location in

mild (ordinary) environmental areas. A version is

available with optional EMC compliance.

NOTE

In regions that require EMC compliance, you

must order the EMC compliance option if

Tricon modules SMM or SRXM will be

installed in a chassis in this enclosure.

Without these modules, the enclosure

already fulfills the requirements for EMC

compliance.

The G60 enclosure, IP 43 rated, can be installed

bayed or adjoined to others to maximize the use of

floor space and ease of cabling. The enclosures can

be bayed together using third-party kits.

This enclosure and its configurations have been

tested and qualified by Invensys for use with the

Tricon chassis.

NOTE

It is possible to configure the G60 enclosure

with front access only and the safety glass

front door. However, since no ventilation is

located on a rear wall, the end-user is

responsible for locating adequate inlet

ventilation to maintain proper operation of

the enclosure’s equipment, through

ventilation on a side wall or from an adjoined

cabinet.

Vented enclosures have a limited thermal load (see

“Operating Temperatures (Ambient)” on page 8).

INGRESS PROTECTION

The metal enclosures provide the outer layer of

protection for the control electronics. Other layers are

provided by the module covers and built into the

modules. This approach to protection means that a

minimum of contaminants in the plant environment

reaches the control components, thus greatly

extending the life of the equipment.

DUAL THERMOSTAT

An optional dual (high/low) thermostat is available to

monitor enclosure temperature extremes.

DOOR INTRUSION MONITORING

An optional door intrusion monitoring switch is

available for each door on the enclosure. Each switch

is prewired to a set of alarm status terminal blocks.
