Overall Review P2S200TCPDG2BEC
The Power Distribution Module (TCPD), distributes the 125 V dc power to the TCPS boards in each
I/O core. The TCPD board provides switches for powering down each core individually. The digital I/O cores , these cores get their power from there. The 120/240 V ac for the ignition transformers is supplied by the TCPD board.
