The Contact Output Expansion Termination Module (DTBD) is located in the and the cores. The DTBD terminal board receives contact output signals 31 through 60. These signals get their inputs from the TCRA board in location five of the respective core or . Sixteen of the 30 relays can be configured to be solenoids using hardware jumpers on the DTBD board to “wet” (power) them. Two additional relays can be wetted using the J19 and J20 connectors in either the or the cores. These contact outputs (#47 and #48) are typically used for ignition transformers. Figure 5-24 shows a typical layout of the DTBD terminal board.
