Product: ABB 83SR07A-E GJR2392700R1210 Control Module

Description

Application

This module can be used to implement input and processing module redundancy in the PROCONTROL system.

As a supplement to the updated module description for the module 83SR07 ---E/R1210, this document focusses on the module’s redundancy --- related features.

Features

Processing is performed in parallel in the on ---line and standby units. When a redundancy switchover is effected, this results in a bumpless transfer of the processing functions to the standby unit.

This bumpless changeover is ensured by synchronizing the standby unit with the on ---line unit by means of synchronizing telegrams.

Both on ---line and standby units are self ---monitoring. Any disturbances within the modules are signalled to the appropriate redundancy control module 88TR01 via the SSG line.

All process connections (connectors X21) of the individual modules belonging to a redundant pair are connected in parallel by appropriate wiring in the station.

The input resistors (burdens) are connected in the on ---line unit and disconnected in the standby unit. This is also true for the process outputs and for the transducer and contact supplies from the module.

For diagnostic purposes, standby units transmit a sign ---of ---life telegram on the bus.
