88QT03C-E is ABB PROCONTROL system Coupling Module. The bus coupling module 88QT03 connects the station bu sand the input/output station. The following input/output station modules can be connected: -70EA01-E/R1 Analog input module(one data telegram per function unit) -70EA02-E/R1 Analog input module (one data telegram per function unit) -70EB01-E/R1 Binary input module (one data telegram per module) -70EB02-E/R4 Binary input module (one data telegram per module) -70EB03-E/R1 Binary input module (one data telegram per module) -70ER01/R1 Input module for checkback signals(one data telegram per module) -70AA01/R1 Analog output module (four data telegrams per module) -70AA02/R1 Analog output module (four data telegrams per module) -70AB01-E/R1，R2 Binary output module (one data telegram per module) -70PR03-E/R1，R2 Computing module -70AS04/R1 Compact drive control module -70AS06/R1 Compact drive modulefor motor-driven actuators -70WB01/R1 Control room coupling module(two data telegrams per module) -70BK03-E/R1，R2 Bus coupling module(RS232,RS485 interfaces) Connected to the station bus, the module behaves like a combined input/output module which is able to receive max. 255 telegrams from the station bus and transmit max. 200 telegrams to the station bus.
In relation to the input/output station the module acts as a processing module. lt receives and transmits a total of up to 256 telegrams. In conjunction with the module 88QB03-E/R0100 the buscoupling module can be installed in the PROCONTROL cabinets 89MS01 and 89MS02, too.
