Frequently Asked Questions about DS200DDTBG2A

What is the function of a DS200DDTBG2A LCI Auxiliary Terminal Board?

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. 

Are there differences between the DS200DDTBG1A and DS200DDTBG2A boards?

Yes. The DS200DDTBG1A board has a few more features than the DS200DDTBG2A board and any information needed to determine the difference in which model is best for you can be found in the GEI-100219 LCI Auxiliary I/O Terminal Board Users Guide.

What are the high current relay outputs on the DS200DDTBG2A board?

The high current relay outputs on the DS200DDTBG2A board are labeled as digital I/Os. The two form-C relay outputs are created for 20 amps at 240 VAC or 10 amps at 30 VDC, both of the outputs have contacts available on the screw terminals and also have a LED indicator that will be lit when the relay has been picked up. Please note that driven loads of this function will be suppressed externally. 

How many connectors are there and what are their types?

There are six connectors, which are labeled as follows, TBPL, TB5, TB4, TB3, TB1, and, TB2. The TBPL connector is a 60-pin high-density ribbon cable header, the TB5 connector is a 6-position terminal strip and clamp, connectors TB3 and TB4 are both 3-position terminal strips and calms, and connectors TB1 and TB2 are 36-position double-row connectors.

How many universal isolated discrete inputs are there? What are their purposes?

There are a total of eight universal isolated discrete inputs, they are used to respond to 24-250 VDC/ 24-230 VAC at 60 HZ, or 125-230 at 50 Hz.

Product Description

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. If any questions arise please refer to the GEI-100219 manual for part specifications and refer to the GEH-6373 series manual for questions regarding the attached parts. 

Reviews For DS200DDTBG2A

Internal Review

The DS200DDTBG2A model is the second of two DDTB models, this model lacks some functionality of the G1 and will be noted within the GEI-100219 manual where applicable. Additionally, because of less G2 models installed by the manufacturer, there are less replacement surplus models available should one be required to replace a defective DS200DDTBG2A in an application. - AX Control Technician
