Product: 88QB03 GJR2393800R0100 88QB03B-E ABB Coupling Module

Description

88QB03B-E is always installed in the PROCONTROL cabinets 89MS01/R0100/R0200/R0300/R0400 and 89MS02/R0100 in connection with module 88QT03-E/R2111. The module is required to installed directly on the right of the module 88QT03-E/R2111 seen from the front of the cabinet. Both modules shall be installed in a 24 V subrack.

Installation of the module in the subracks together with89NG03, i.e. 89MS01/R0100/R0200, BGT:D and 89MS01/R0300/R0400,BGT:Gis not permissible(standard).

If in contrast with this standard further subracks are retrofit with 89NG03 in these subracks, too installation of this module is not permissible.

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 (see 'Module adjustment').
