The Contact Output Termination Module (DTBC) is located in the <Q11> and <Q51> cores. The DTBC terminal board receives the first 30 contact output signals. These signals get their inputs from the TCRA board in location four of the respective core <Q11> or <Q51>. Eighteen of the 30 relays on the TCRA board in location four of the <Q51> core can be configured to be solenoids using hardware jumpers on the DTBC board to “wet” (power) them.
