I/O modules

Key Technical Specifications

This GE IS200BCLAH1A IS200BCLAH1ABA motherboard operates from a 24V DC power supply. It provides 32 analog I/O channels for Mark VIe control systems. The unit measures 28 cm in length, 20 cm in width, and 5 cm in height. Its total weight reaches 0.95 kg without any packaging materials.

The GE IS200BCLAH1A IS200BCLAH1ABA includes 16 analog inputs and 16 analog outputs. Additionally, it features one backplane connector for system integration. A single 6-pin terminal block connects the DC power input. The motherboard contains 2 AD converters, 2 DA converters, 1 FPGA, 16 analog conditioners, 8 voltage regulators, 32 resistors, and 24 capacitors.

GE IS200BCLAH1A IS200BCLAH1ABA stores energy using two electrolytic capacitors. Together, they provide 470 µF at 35V rating for output hold-up. This energy storage maintains analog outputs during 30 millisecond power interruptions. Therefore, actuators remain stable through brief voltage dips.

Design and Integration

Both the GE IS200BCLAH1A and IS200BCLAH1ABA versions share identical analog I/O circuitry. These motherboards use six-layer PCB construction with separate analog and digital grounds. Consequently, the GE IS200BCLAH1A IS200BCLAH1ABA operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M4 screws for the four mounting holes. The motherboard draws 450 mA typical current from the 24V DC supply. Each output channel can drive loads up to 20 mA maximum. We recommend using shielded cables for all analog field connections.

Practical Application

This core analog I/O motherboard connects field sensors and actuators to a Mark VIe controller. It reads temperature, pressure, and flow signals from turbine systems. The GE IS200BCLAH1A IS200BCLAH1ABA then sends control outputs to valves and positioners. Therefore, it serves as the primary analog interface for GE turbine control systems.
