Overall Review DS200CTBAG1ADD
The Termination Module (CTBA) terminal board is located in the core. The CTBA terminal board lands the 4–20 mA output signals, the 4–20 mA input signals, and the shaft voltage and shaft current signals. The IONET connection to the STCA board and the COREBUS connection to the QTBA board on the core are also located on the CTBA board. The 24 V dc power for diagnostics comes from the TCPD board in the core. A bypass relay that allows the COREBUS to continue to communicate if power is lost to the CTBA terminal board is located on the CTBA terminal board.
