Select I/O is an Ethernet networked, single-channel granular I/O

system for the ABB Ability™ System 800xA automation platform.

Select I/O helps decouple project tasks, minimizes the impact of

late changes, and supports standardization of I/O cabinetry

ensuring automation projects are delivered on time and under

budget. A Signal Conditioning Module (SCM) performs the

necessary signal conditioning and powering of the connected field

device for one I/O channel.

The AIS885 is an Analog Input Signal Conditioning Module (16-bit)

for use in High Integrity applications (certified for SIL3) supporting

2/3/4-wire devices (1.2 amp) and HART communications.

Features and benefits

• Digital input for 2-wire, 3-wire and externally powered 4-wire field devices

• Can be used in hazardous areas

• Field device power output current limited to 35 mA

• Channel to channel galvanic isolation

• Configurable software signal filter 0…100 ms

• Protected against wrong wiring

• Diagnostics:

– Loop supervision (open circuit and short circuit)

– Communication supervision

– Internal power supervision

• Sequence of Events (SoE)

• DIS801 supports both Normally Open (NO) and Normally Closed (NC) 24 V loops

• Single loop granularity – each SCM handles a single channel

• Supports hot swap

• Mechanical locking slider which turns off field device power and/or output before removal

• Field disconnect function which can galvanically separate the field loop wiring from the SCM during

commissioning and maintenance

• All SCMs have electronic current limitation

• Mechanical keying to prevent insertion of wrong module type after commissioning

• 24V DC powered through Modulebus

• Configurable through parameters

• LED indicators on the SCM indicate the operational state of the module

The DIS801 is a Digital Input 24 V Signal Conditioning Module

supporting 2/3/4-wire devices with Sequence of Events (SOE).

PROFIBUS DP is a high speed multipurpose bus protocol (up to

12Mbit/s) for interconnecting field devices, like remote I/O,

drives, low voltage electrical equipment, and controllers.

PROFIBUS DP can be connected to the AC 800M via the CI854B

communication interface. The CI854B includes two PROFIBUS

ports to realize line redundancy and it also supports PROFIBUS

master redundancy.

Master redundancy is supported in PROFIBUS-DP communication

by using two CI854B communication interface modules. The

master redundancy can be combined with CPU redundancy and

CEXbus redundancy (BC810). The modules are mounted on a DIN

rail and interface directly with the S800 I/O system, and other I/O

systems as well, including all PROFIBUS DP/DP-V1 and

FOUNDATION Fieldbus proficient systems.

The PROFIBUS DP must be terminated at the two outermost

nodes. This is usually done by using connectors with built-in

termination. To guarantee a correct working termination the

connector has to be plugged and power supplied.

Package including: a CI854BK01 Communication Interface and a

TP854 Baseplate.

Features and benefits

• Used for connecting remote I/O and fieldbus instruments via PROFIBUS DP

• Possible to connect PROFIBUS PA to the CI854B via the PROFIBUS linking device LD 800P

• The CI854B can be set redundant

Features and benefits

• Maximum number of MCUs (or other INSUM devices) per AC 800M: – 256 MCUs (or other INSUM

devices) per AC 800M with PM864 or PM866. – 128 MCUs (or other INSUM devices) per AC 800M

with PM861.

• Maximum 6 CI857 per AC 800M.

• Maximum 128 MCUs (or other INSUM devices) per CI857.

• Maximum 2 INSUM TCP/IP Gateways per CI857.

• Maximum 128 INSUM devices per INSUM TCP/IP gateway.

• Four LonWorks subnets per INSUM TCP/IP gateway.

• Maximum 32 devices per LonWorks subnet.

INSUM integration into AC 800M supports higher functionality

integration, multidrop configurations, time distribution and time

stamping in the switchgear, and utilizes standard Ethernet

technology for longer communication distances. The speed of this

solution is typically 500 ms for one closed loop (indication from

one motor until operation of another, assuming 250 ms cycle time

in control execution).

AC 800M controllers access the INSUM functions through function

blocks in the INSUM Communication Library. The CI857 is powered

by the processor unit, via the CEX-Bus, and therefore does not

require any additional external power source.

Features and benefits

• CI874 supports connection with OPC UA servers

• CI874 can be configured as redundant

• User can perform the upgrade of CI874 software components, called as online upgrade

• CI874 has a Web Server Interface who offers access to CI874 specific information used during

commissioning and maintenance

• CI874 supports hot swap without any configuration changes

The CI874 is an AC 800M communication interface that connects

to external Ethernet devices using the OPC UA protocol. The TP867

Baseplate has one RJ45 Ethernet connector that supports

100Mbps. The CI874 expansion unit contains the CEX-Bus logic, a

communication unit, and a DC/DC converter that supplies the

required voltage from +24 V supply through the CEX-Bus.

CI874 is represented as a hardware module within the Control

Builder hardware tree. The CI874 module will only work with System

800xA 6.1.1 and subsequent versions.
