I/O modules

Key Technical Specifications

This GE IS200REGIH1A IS200REGIH1ABR6 board accepts a 28V DC power input. It delivers 5A continuous output current for turbine regulation systems. The unit measures 25 cm in length, 18 cm in width, and 6 cm in height. Its total weight reaches 1.2 kg without any packaging materials.

The GE IS200REGIH1A IS200REGIH1ABR6 includes six analog input channels for sensor readings. Additionally, it features four discrete output channels for actuator control. A single 37-pin D-sub connector handles all I/O signals. The board contains 3 voltage regulators, 8 operational amplifiers, and 15 resistors.

GE IS200REGIH1A IS200REGIH1ABR6 stores energy using two parallel electrolytic capacitors. Together, they provide 1000 µF at 40V rating for hold-up time. This energy storage supports power interruptions up to 30 milliseconds. Therefore, the board maintains turbine control during brief voltage sags.

Design and Integration

Both the GE IS200REGIH1A and GE IS200REGIH1ABR6 versions use identical circuit topology. These boards employ six-layer PCB construction for superior signal integrity. Consequently, the GE IS200REGIH1A IS200REGIH1ABR6 operates reliably from -20°C to +65°C ambient temperature.

For installation, you need M4 screws for the six mounting holes. The board draws 200 mA typical current from the 28V supply. During startup, it briefly consumes 350 mA for less than one second. We recommend using a 2A fast-acting fuse for input protection.

Practical Application

This turbine control board monitors speed, temperature, and vibration sensors continuously. It processes analog signals from four thermocouples and two accelerometers. The GE IS200REGIH1A IS200REGIH1ABR6 sends control outputs to fuel valves and inlet guide vanes. Therefore, it enables precise turbine speed and load regulation.
