DS200DDTBG2A GE LS2100, Auxiliary Input Output Terminal Board

Description:

The DS200DDTBG2A functions as a high voltage terminal board and facilitates the connections of auxiliary I/O signals by connecting to the DS200ADMA analog to digital option board in an LS2100 control system. 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 DS200DDTBG2A model is the second version of the DS200DDTB model which is part of the LS2100 series from General Electric. One of the functions of this model is to provide scaling, buffering, signal conditioning, and isolation to make the environment system-level signals attainable to the DSPC’s digital signal processor. The model includes two high voltage AC inputs that use passive filtering, a step-down transformer, and a buffer to provide a ±5 V peak-to-peak signal to the attached analog-to-digital module to VCO inputs which will run at 693 VRMS. 

The DS200DDTBG2A model is equipped with twelve three-pin row jumpers. Each jumper has an individual setting as well as individual functions. Several other features within the DDTB model are the high-voltage and high-current inputs, as well as low-current signal inputs as well. When it pertains to the high-current inputs there are six that have current resistors which are suitable for continuous current signals.

The DS200DDTBG2A model also has four optically isolated state outputs which are rated at a maximum of forty-eight volts and will read at 10 mA’s each.
