ABB CI862 Classic COMMUNICATIONS - AC 800M COMMUNICATION INTERFACES

TRIO, interface integrates TRIO/Genius I/O as a native AC 800M I/O.

The TRIO interface to the AC 800M is via the CI862 CEX module.

This module supports direct connection for one TRIO LAN and provides a port for the Hand Held Monitor.

A single CI862 can connect 30 blocks to a single LAN.

The AC 800M can have up to four single LANs or four redundant LANs.

The maximum I/O with TRIO in an AC 800M is 1000 IO points.

The CI862 can be set redundant. The CI862 is the communication interface to

the TRIO blocks (remote I/O) and manages the channel data for the AC 800M controller.

Features and benefits The AC 800M controller supports up to four CI862 CEX modules and 1,000 TRIO/Genius I/O points.

TRIO supports CEX module redundancy. The CI862 unit also handles the I/O configuration and I/O scanning of up to 30 TRIO blocks.

The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. 

For instance, one REC670 IED is capable of handling control of all apparatuses 

in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.

The REF 543 feeder terminal is designed for protection, control, 

measurement and supervision in medium voltage networks.

The REF 543 feeder terminal can be used with different kinds of switchgear, 

including single busbar, double busbar and duplex systems.

The protection functions also support different types of networks, such as, isolated neutral networks, 

resonant-earthed networks and partially earthed networks. 

REC670 IEDs (Intelligent Electronic Device) provide control solutions for any type of switchgear and different switchgear configurations. 

The customized REC670 gives you the freedom to select the functionality entirely according to your needs. 

The pre-configured REC670 variants simplify handling since the basic functionality is included and pre-configured. 

If needed, you can add optional functions to easily increase the functionality of 

the REC670 IEDs to meet the specific requirements of your switchyard.

REC670 integrates advanced voltage control for transformers in a substation in a single IED. 

The IEDs feature a large HMI for local control and instant access to important data, 

such as settings, events and disturbance information.
