I/O modules

The GE IS200EMIOH1A IS200EMIOH1AFB PC Board serves as a multifunctional I/O interface for turbine control. This board handles both discrete inputs and discrete output signals. You will find it managing auxiliary equipment like pumps and fans. It integrates seamlessly into the GE Mark VI series architecture.

Core Technical Specifications

The GE IS200EMIOH1A IS200EMIOH1AFB PC Board measures 31.0 cm in width and 23.5 cm in height. Its board thickness equals 2.2 cm including component clearance. The total assembly weighs approximately 0.55 kilograms. Thirty-two configurable I/O points populate the board’s surface. Sixteen channels serve as discrete inputs. The remaining sixteen channels act as discrete outputs.

Connectors and Status Indicators

The GE IS200EMIOH1A IS200EMIOH1AFB PC Board uses one 64-pin DIN connector for backplane signals. This connector carries all I/O data to the VCRC processor. Two 37-pin D-sub connectors handle field wiring for inputs and outputs. Thirty-two green LEDs show the status of each I/O point. A red LED indicates a blown fuse on the output power rail. Moreover, a yellow LED confirms 24 VDC logic power presence.

Energy Storage and Protection Circuits

This PC board contains small filtering capacitors only on the power inputs. Therefore, it stores minimal residual energy after system shutdown. Each output channel includes a self-resetting PTC fuse for overload protection. This feature prevents damage from field wiring shorts. Furthermore, the GE IS200EMIOH1A IS200EMIOH1AFB PC Board integrates optocoupler isolation on all inputs. This isolation separates the logic ground from field ground. You can configure each channel as input or output via jumpers. Do not exceed 0.5 A on any output channel continuously. Use external relays for loads above this current rating.
