88QB03B-E ABB GJR2393800R0100 Bus Termination Module

Description:

Abb GJR2393800R0100 88QB03B-E is a dedicated bus terminal module for distributed control system of procontrol P. Its main function is to stop the quantity end of procontrol P mother ship to prevent the reflection of signal and ensure the optimal transmission of signal. In addition, the impedance of the mothership kevl and the impedance of the mothership electronics were interlocked to improve the overall performance of the system.

Features:
-The module incorporates the bus termination for connection of 88QT03 to the PROCONTROL-PS bus and/or the input/output station and the central clock-pulse supply for 88QT03.
-It is supplied by a dual 24 V(USA, USB) supply
-Power supplies ofthe termination resistors and the circuit section for the central clock pulse are generated on the module from 24 V by separate power supply modules. The voltage for the termination resistors is monitored.
-Connection to 88QT03 is by means of the process connector.
If several 88QB03 modules are installed in a subrack the central clock pulse can be disconnected by removing a plugin jumper on the module.
-For use in the subracks of the different PROCONTROL cabinets the module is provided with an additional plugin jumper by means of which the termination resistors for the centra clock can be switched on or off.
