PLCs, Power Supplies & Others

The GE DS200SPCBG1A DS200SPCBG1ADC condition analog signals from multiple power bridges. These multi-bridge signal processing boards serve the GE Mark V Turbine Control System. You can use either board to process voltage and current feedback from SCR bridges. The units provide filtering, scaling, and isolation for accurate measurements.

Signal Processing Specifications

The GE DS200SPCBG1A DS200SPCBG1ADC process 12 differential analog input channels. These multi-bridge signal processing boards accept ±10 VDC or 4-20 mA signals. You can configure each channel independently for voltage or current mode. The units provide 16-bit resolution for high-accuracy measurements.

Physical Dimensions and Weight

Each multi-bridge signal processing board weighs 0.56 kg for secure chassis mounting. The unit measures 280 mm long by 178 mm wide. Its PCB thickness reaches 1.6 mm with six internal copper layers. You can mount either board using six M4 screws through the designated holes.

Interface and Connection Points

Three 50-pin ribbon cable headers connect to the main turbine controller. Six 2-pin terminal blocks provide field wiring access for analog signals. The GE DS200SPCBG1A DS200SPCBG1ADC include a 4-pin power input connector. You will find 12 LED indicators showing signal presence on each channel. Additionally, sixteen test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These multi-bridge signal processing boards store minimal energy for filtering purposes. Twenty-four electrolytic capacitors provide 470 µF of total bulk storage. These capacitors smooth power supply ripple for the analog circuits. The boards do not contain any battery for configuration retention. An onboard EEPROM stores calibration data for each channel.

Component Layout and Construction

A 16-bit analog-to-digital converter serves all 12 channels via a multiplexer. Twelve precision operational amplifiers condition each input signal individually. You will find 168 resistors, 96 capacitors, and 14 integrated circuits on the board. The GE DS200SPCBG1A DS200SPCBG1ADC include transient protection on all input channels. A metal shield covers the analog section for noise reduction.

Variant Equivalence and Use

The GE DS200SPCBG1ADC represents a functional equivalent or later revision. Both versions share identical dimensions, connectors, and mounting hole locations. You can substitute one for the other without hardware modifications. Transitioning to these boards restores signal conditioning to Mark V systems. Use GE DS200SPCBG1A DS200SPCBG1ADC for power bridge feedback in turbine control applications. For best results, use shielded twisted-pair cables for all analog input
