General Electric Speedtronic Mark V DS200DDTBG2A is an LCI Auxiliary I/O Terminal Board (DDTB) and is a part of gas turbine control systems. This high-voltage board connects peripheral and auxiliary input/output signals to the system. It's simple to install on a DSPC that already has an ADMA daughterboard mounted. The ADMA is connected to the board using ribbon cables and high-density connectors. When the DS200DDTBG2A is inserted into a drive, it provides a number of I/O ports. The card has a number of different analog and digital I/O slots. One of the two isolated inputs can be used to connect high voltage AC signals.
