Function description:
DS200DDTBG1A is an LCI auxiliary I/O terminal board manufactured and designed by General Electric, belonging to the Mark V series used in GE Speedtronic control systems. DS200DDTB board (DDTB) is a high-voltage terminal board used for auxiliary I/O signal system connections. This board is connected to the DS200ADMA (ADMA) analog to digital module sub board installed on the DS200DSPC (DSPC) digital signal processor control board. High density connectors and ribbon cables connect the DDTB to the ADMA board. The power supply for DDTB is provided by the ADMA board. DDTB provides signal conditioning, scaling, buffering, and isolation to make harsh environment system level signals accessible to the digital signal processor (DSP) of the DSPC board. External wiring connections for high-voltage signals, contact I/O, current measurement (via low-level Hall effect devices), or high current CT can be connected to the DDTB terminal. The DDTB board has G1 and G2 versions. G2 lacks some functions of G1 and has provided explanations where applicable.
Features:
High voltage AC input: There are two isolated inputs used to connect high-voltage AC signals. They use step-down transformers, passive filters, and buffers to provide ± 5 V peak to peak signals (applying 693 V root mean square value) to the VCO input of the ADMA board. These inputs have separate screw terminals with a rated and isolated voltage of 1000 V peak transient.
High current signal input: There are six charged current response resistors for input, suitable for ± 5 ampere continuous current signals (for CT input). These inputs use differential buffering and can withstand ± 12V common mode voltage. Each input is filtered and scaled. These inputs have screw type terminal blocks and are protected against voltage surges.
Low current signal input: There are three charged current response resistors for input, suitable for ± 0.224 ampere continuous current signals (used for LEM current sensor signals). These inputs use differential buffering and can withstand a common mode voltage of ± 12 V. Each input is filtered and scaled. These inputs have screw type terminal blocks and are protected against voltage surges.
4-20 mA current loop input: There is a requirement to reassign two of the CT or LEM input channels to a 4-20 mA current loop input signal receiver. This alternative allocation is done by resetting certain jumpers. The input resistance is 192 ohms, and the analog input is offset, so 0 mA produces negative full-scale and 20 mA produces positive full-scale. Open loop detection and input standardization are managed by software.
Non dedicated voltage input: Provides a differential input voltage amplifier for powering the analog VCO input on the ADMA board. The gain of this amplifier is 1/2, allowing for a ± 10 V input signal range. These inputs have screw type terminal blocks and are protected against voltage surges.
4-20 mA current output: Two analog outputs also drive the current source output buffer to support the 4-20 mA current loop output signal. The voltage and current outputs are always active and can be used separately or together by connecting to their respective output terminals. There is an inversion and gain stage in the 4-20 mA driver, so a+5 V input from the ADMA board will result in an output of 4 mA, while a -5 V input will result in an output of 20 mA. Output of 0 mA is not allowed to avoid confusion with open-loop detection.
The DS200DDTBG1A model is known as an auxiliary input/output terminal board, and information about it can be found on page 20 of the GEH-6373 series manual. This model is most suitable for use as a terminal board for all auxiliary inputs and outputs. There is a parts manual labeled GEH-100219, which provides detailed information on functions, general characteristics, application data, as well as warranty and replacement information.
In the DS200DDTBG1A model, there is an electronic ID memory function that can only be added, which includes all circuit board identification and hardware revision information. To access this memory, you must use a single wire LAN so that the connected DSPC circuit board can recognize the circuit boards present in the system.
The DS200DDTBG1A model is equipped with a 4-20 mA current loop input, allowing for reassignment of LEM or CT input channels within the model. To perform this function, certain jumpers must be reset. This model is also equipped with 33 testing points, which can be used for signal measurement. This model has a total of 17 LEDs, with one LED on the board indicating the status of the DS200DDTBG1A board, while the other fifteen LEDs are driven by software and hardware.
