I/O modules

Key Technical Specifications

This GE IS200SSCAH2A IS200SSCAH2AEC board operates from a 24V DC power supply. It provides 32 mixed I/O channels for signal termination. The unit measures 22 cm in length, 17 cm in width, and 4.5 cm in height. Its total weight reaches 0.75 kg without any packaging materials.

The GE IS200SSCAH2A IS200SSCAH2AEC includes 16 digital inputs, 8 digital outputs, and 8 analog inputs. Additionally, it features one 50-pin ribbon connector for host interface. A single 6-pin terminal block connects the DC power input. The board contains 1 FPGA, 16 optocouplers, 8 analog conditioners, 8 LED drivers, 24 resistors, and 16 capacitors.

GE IS200SSCAH2A IS200SSCAH2AEC stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 25 millisecond power interruptions. Therefore, the board prevents false switching in industrial environments.

Design and Integration

Both the GE IS200SSCAH2A and IS200SSCAH2AEC versions share identical I/O circuitry. These boards use four-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE IS200SSCAH2A IS200SSCAH2AEC operates reliably from -10°C to +55°C ambient temperature.

For installation, you need M3 screws for the four mounting holes. The board draws 300 mA typical current from the 24V DC supply. Each analog input includes software selectable ranges. We recommend using shielded cables for all analog field connections.

Practical Application

This I/O terminal board connects field devices to a turbine or drive controller. It terminates digital and analog signals from sensors and actuators. The GE IS200SSCAH2A IS200SSCAH2AEC then routes conditioned signals to the main processor. Therefore, it serves as a flexible termination interface for GE control systems.
