The RIU2 supports 10/100MB communication on both primary

and secondary ports.

Data Passthrough. The controller is equipped with the

ability to pass smart HART® information from field devices

connected to a Remote I/O Unit to any workstation node

in the control network.

This means you can take advantage of applications, such as

AMS Device Manager that enable you to remotely manage the

HART information contained in your HART equipped devices.

Mounting. This plug-and-play system structure provides

modular system growth with a single controller and

is approved for remote mounting in a Class 1. Div 2 or

ATEX Zone 2 environment. Refer to the System Power

Supplies and I/O Subsystem Carriers product data sheets

for additional information.

I/O Types and Capacity. The RIU2 support one I/O carrier

of either Classic I/O or HART I/O. The Remote I/O Unit and

I/O cards can be installed on either horizontal or VerticalPlus

carriers. Any of the Classic or HART I/O cards may be utilized.

The HART data from the I/O channels can be used in a control

strategy, providing the user with the same experience using

remote I/O as when using local I/O.

Shared remote I/O for maximum flexibility

I/O Targeting. The M-series Zone 2 Remote I/O Units supports

targeting of Classic I/O to controllers on a per card basis.

For example, a card can be owned by a controller, with different

I/O cards owned by a different controller, with the limit that a

Remote I/O Unit can support 4 controllers maximum.

Each DeltaV controller can have up to 16 Remote I/O Units

associated with it.

The DeltaV system supports up to 300 remote I/O Units1

and they communicate on the same Ethernet network as

the controllers and workstations.

The RIU2 supports 10/100MB communication on both primary

and secondary ports.

Data Passthrough. The controller is equipped with the

ability to pass smart HART® information from field devices

connected to a Remote I/O Unit to any workstation node

in the control network.

Product Description

The DeltaV M-series Zone 2 Remote I/O delivers big savings

in the installation process. The compact, modular design

allows you to cost-effectively meet your process needs.

The Remote I/O subsystem consists of a System Power

Supply and a Remote I/O Unit connected to an 8-wide I/O

carrier with up to 8 simplex I/O cards.

There are two versions of the Remote I/O Unit; the original

Remote I/O Unit (RIU), and the Next Generation Remote I/O

Unit 2 (RIU2). The RIU2 is a drop-in replacement for the

original RIU back to DeltaV v13.3.1 and has the same

functionality as the original RIU.

Easy to use

Total Control. The controller(s) manages all control

activities for the I/O interface channels. It also manages all

communication functions for the communications network.

Time stamping, alarming, and trend objects are also managed

within the controller(s). The controller(s) executes your control

strategy. Information from an input channel on a Remote I/O

Unit is received, control strategy applied, and data is sent to an

output channel on Remote I/O Unit within 200 ms on average –

assuming a 100 ms scan time for the I/O.

Introduction

The DeltaV™ M-series Zone 2 Remote I/O architecture allows

I/O cards to be installed remotely from the controller and

provides communication and control between the field

devices connected to the Remote I/O subsystem and the

other nodes on the control network. Control strategies

and system configurations reside in the DeltaV system’s

powerful controllers.

Benefits

Shared remote I/O. DeltaV M-series Zone 2 Remote I/O can be

shared amongst several DeltaV controllers for a greater range

of applications and installation flexibility.

Easy plug-and-play installation. DeltaV M-series Zone

2 Remote I/O automatically identifies itself to the control

network, saving the usual no-value engineering work that

other automation systems require. Additionally, I/O cards are

recognized as they are inserted into the Remote I/O subsystem.

Easy to use. Like the traditional I/O in your DeltaV system,

the DeltaV controller manages all activities for your Zone

2 Remote I/O. The I/O cards supported by the Remote I/O

subsystem are the same as those used on M-series controllers –

saving you spares.

The PR 6423 is a non-contact eddy current transducer with a rugged

construction and designed for extremely critical turbomachinery

applications such as steam, gas, compressor and hydro turbomachinery,

blowers and fans.

The purpose of a displacement probe is to measure position or shaft

movement without contacting the measured surface – the rotor.

In the case of sleeve bearing machines, the shaft is separated

from the bearing material by a thin film of oil. The oil acts as

a dampener and therefore the vibration and position of the shaft

are not transmitted through the bearing to the bearing case.

The use of case vibration sensors is discouraged for monitoring

sleeve bearing machines since the vibration produced by shaft motion

or position is greatly attenuated through the bearing oil film.

The ideal method of monitoring shaft position and motion is by

mounting a non-contact eddy sensor through the bearing, or

inside the bearing, measuring the shaft motion and position

directly.

Features

• Cost Effective—Single trip valve construction

reduces costs and spare part requirements of those

systems using three separate switching valves to

perform the failure functions. A single trip valve

greatly simplifies piping requirements.

• Ease of Mode Conversion—Conversion to any of the

fail modes requires only minor hookup changes.

• Adjustable Trip Valve—The trip point is adjustable

for specific supply pressure requirements.

• Reliable Operation—The trip valve design includes

large diaphragm areas and few moving parts for

efficient performance, minimum maintenance, and

long service life.

Specifications

Available Configurations

When supply pressure falls below the trip point,

377D Trip Valve: Fails actuator piston down. Includes

check valve and volume tank.

377L Trip Valve: Locks actuator piston in the last

position.

377U Trip Valve: Fails actuator piston up. Includes

check valve and volume tank.

377CW Trip Valve: Fails fully clockwise to close the

valve. Requires check valve and volume tank. Trip

valve moves piston to either up/down position and

requires actuator configuration for actual clockwise

movement.

377CCW Trip Valve: Fails fully counterclockwise to

close the valve. Requires check valve and volume

tank. Trip valve moves piston to either up/down

position and requires actuator configuration for

actual counterclockwise movement.

All 377 trip valves can be converted to any of the

above fail modes with minor hookup changes

Fisher™ 377 Trip Valve

Fisher 377 pressure‐sensing trip valves are for control

applications where a specific valve/actuator action is

required when supply pressure falls below a specific

point. When supply pressure falls below the trip point

(see figure 1), the trip valve causes the actuator to fail

up, lock in the last position, or fail down. When the

supply pressure rises above the trip point, the 377 trip

valve automatically resets, allowing the system to

return to normal operation. The trip valve can be

top‐mounted on a manifold, yoke‐mounted, or

bracket‐mounted to match the application

requirements. 377 trip valves can be used with Fisher

480. 585C, 685. 1061. 1066. 1069. and Bettis™ G

Series piston actuators.

Introduction 

If concerns about downtime and wiring costs are preventing 

you from migrating your Foxboro™ I/A Series 100 I/O to a new 

DeltaV™ system, consider DeltaV Flex.Connect solutions for 

Foxboro I/A Series 100 I/O. 

Benefits 

Reduce business risks by minimizing process downtime. This 

solution brings device signals to DeltaV I/O from existing Foxboro 

I/A Series 100 Fieldbus Modules (FBMs). Keeping device 

wires intact accelerates the new system startup, enabling you to 

rapidly resume production. 

Save installation costs. Eliminating new device wiring saves money 

and reduces the risk of errors. Time and material savings are 

significant. 

Preserve HART signals. Use HART® Pass-through for complete 

diagnostics at the DeltaV workstations.
