DS200DDTBG1A GE LS2100, Auxiliary Input Output Terminal Board

Description:

The DS200DDTBG1A is a LCI Auxiliary I/O Terminal Board used in GE LS2100 Control Systems. The DDTB is a base-mounted interface board for system connections of auxiliary I/O. These can include voltage signals, contact I/O, current measurement signals, and current transformer (CT) input. The board provides signal conditioning, scaling, buffering, and isolation functions. The DDTB connects to the ADMA board, which is a DSPC daughterboard. For more detailed information on the DDTB, see publication GEI-100219.

The board derives power from the attached ADMA board. It features high voltage AC inputs, high current signal inputs, low current signal inputs, 4-20 mA current loop inputs, and undedicated voltage inputs, which are provided through a differential input voltage amplifier to an analog VCO input on the ADMA board, protected by screw-type terminal blocks. There are 12 jumpers on the board for reassigning LEM and CT input channels as 4-20 mA current loop signals. Additionally, it has four buffered analog voltage outputs at screw terminals, each with a 200-ohm series resistor and a gain of two, providing a ±10 V output range from the ±5 V from the ADMA board.
