I/O modules

Key Technical Specifications

This GE IS200VTURH1A IS200VTURH1ADE board operates from a 24V DC power supply. It provides 32 mixed I/O channels for turbine regulation tasks. The unit measures 24 cm in length, 17 cm in width, and 5 cm in height. Its total weight reaches 0.9 kg without any packaging materials.

The GE IS200VTURH1A IS200VTURH1ADE includes 16 digital inputs, 8 digital outputs, and 8 analog inputs. Additionally, it features one Ethernet port for network communication. A single 50-pin header connects to the backplane for power and data. The board contains 1 processor, 2 FPGAs, 8 optocouplers, 4 relay drivers, and 32 resistors.

GE IS200VTURH1A IS200VTURH1ADE stores energy using two parallel electrolytic capacitors. Together, they provide 330 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 25 millisecond power interruptions. Therefore, the board prevents spurious relay dropouts during voltage sags.

Design and Integration

Both the GE IS200VTURH1A and GE IS200VTURH1ADE versions share identical control logic. These boards use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE IS200VTURH1A IS200VTURH1ADE operates reliably from -15°C to +60°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 250 mA typical current from the 24V supply. Each digital output can drive inductive loads up to 0.5A with built-in snubbers. We recommend using separate cable trays for power and signal wiring.

Practical Application

This control board manages turbine speed, load, and temperature loops in real time. It reads speed probes, thermocouples, and pressure transmitters continuously. The GE IS200VTURH1A IS200VTURH1ADE then sends commands to servo valves and trip solenoids. Therefore, it serves as the primary controller for GE steam and gas turbines.
