PLCs, Power Supplies & Others

The GE DS200UCPBG5A DS200UCPBG5ADA interface between turbine sensors and the main controller. These turbine input output boards serve the GE Mark V Turbine Control System. You can use either board to monitor temperatures, pressures, and speeds. The units provide signal conditioning and isolation for critical turbine parameters.

I/O and Electrical Specifications

The GE DS200UCPBG5A DS200UCPBG5ADA monitor 16 analog inputs and 8 thermocouple channels. These turbine input output boards also accept 4 RTD inputs for temperature measurement. You can connect 16 digital inputs and 8 digital outputs for control tasks. The units provide 16-bit resolution for high-accuracy analog readings.

Physical Dimensions and Weight

Each turbine input output board weighs 0.68 kg for secure chassis mounting. The unit measures 305 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. Eight 3-pin terminal blocks handle thermocouple and RTD wiring. The GE DS200UCPBG5A DS200UCPBG5ADA include a 6-pin connector for digital I/O signals. You will find 28 LED indicators showing status for each channel. Additionally, sixteen test points provide access for diagnostic measurements.

Energy Storage and Internal Circuitry

These turbine input output boards store minimal energy for signal filtering. Twenty electrolytic capacitors provide 680 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 all analog channels.

Component Layout and Construction

A 16-bit ADC with multiplexer serves all analog and thermocouple inputs. Eight precision instrumentation amplifiers condition thermocouple signals with cold junction compensation. You will find 186 resistors, 124 capacitors, and 18 integrated circuits on the board. The GE DS200UCPBG5A DS200UCPBG5ADA include transient protection on all I/O points. A metal shield covers the analog section for noise reduction.

Variant Equivalence and Use

The GE DS200UCPBG5ADA 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 I/O functionality to Mark V systems. Use GE DS200UCPBG5A DS200UCPBG5ADA for turbine monitoring in power generation applications. For best results, use shielded thermocouple extension wires for temperature inputs.
