IS220PDIOH1A
Product Name
General Electric (GE) IS220PDIOH1A Digital Input/Output Module (As a versatile signal processing component in GE’s Mark VIe control system, specialized in bidirectional digital signal transmission for industrial machinery, it serves as the “digital interface hub” in power generation, oil & gas, and heavy industry applications)
Product Description
The IS220PDIOH1A is a digital input/output module developed by General Electric, designed for seamless integration into the Mark VIe distributed control system (DCS) used in turbine, generator, and industrial process control. In a gas turbine power plant, this module acts as a critical interface between the central controller and field devices: it receives digital input signals from limit switches, pressure switches, and status sensors to monitor equipment states (e.g., valve position, filter clogging), while simultaneously sending digital output commands to solenoids, relays, and motor starters to execute control actions (e.g., opening/closing valves, activating alarms).
Featuring a combination of 16 digital input channels and 16 digital output channels, the module supports both sinking (NPN) and sourcing (PNP) configurations, enabling compatibility with a wide range of industrial sensors and actuators. This flexibility eliminates the need for additional signal converters, simplifying system design and reducing installation costs. The module incorporates advanced noise filtering and surge protection to withstand electrical interference from high-voltage equipment, ensuring reliable operation in harsh industrial environments with significant electromagnetic noise.
