The IS220PDIOH1A receives discrete contact signals from field devices and transfers the acquired information to the Mark VIe control system. It supports up to 24 contact inputs for monitoring equipment status and field conditions.
The module controls up to 12 relay outputs. These outputs can be used for discrete control commands and equipment interface functions according to the connected terminal board configuration.
The PDIO pack provides dual RJ-45 Ethernet connections for communication with one or two I/O Ethernet networks. This interface supports integration with the distributed Mark VIe control architecture.
LED indicators provide visual information about module operating status. Internal diagnostic functions help detect hardware and communication-related problems.
The module connects directly to compatible GE discrete I/O terminal boards through its DC-62 connector. Supported terminal board combinations include IS200TDBSH2A and IS200TDBTH2A.
The GE IS220PDIOH1A is commonly used in industrial control applications requiring reliable discrete signal acquisition and output control. Typical applications include:
- Gas turbine control systems
- Steam turbine control systems
- Power generation facilities
- Industrial equipment monitoring
- Turbine auxiliary systems
- Discrete equipment interlocking
- Industrial process control
- Distributed control system (DCS) installations
The GE IS220PDIOH1A is a PDIO Discrete Input/Output Pack used in the GE Mark VIe turbine control system. It provides an interface between I/O Ethernet networks and compatible discrete I/O terminal boards.
It supports up to 24 contact inputs and controls up to 12 relay outputs.
The documented compatible terminal boards include IS200TDBSH2A and IS200TDBTH2A. Verify the hardware revision and system configuration before replacement.
The module uses a nominal 28 V DC supply, with a specified range of 27.4–28.6 V DC and a maximum current of 0.81 A DC.
