The Contact Input Termination Module (DTBA) is located in the <Q11> and <Q51> cores. The DTBA terminal board lands the first 46 contact input signals. These signals are typically normally open contacts, but can be inverted to represent a normally closed signal by the I/O configuration software on the TCDA board. A coil for power loss is also located on this board.
