GE Industrial Control Network Interface and I/O Execution
The IS220PSVOH1A uses GE Mark VIe IO Pack architecture to process servo control signals between the control network and field actuator circuits. The module integrates an Intel Celeron 650 MHz processor and 128 MB SDRAM to execute local signal handling tasks.
Additionally, the module supports Ethernet communication through two dedicated ports. Therefore, it can exchange control data with the Mark VIe control system while maintaining distributed I/O operation. The module design supports I/O density scaling through modular IO Pack installation and maintains compatibility with GE industrial control firmware environments.

Field Installation Guidelines
- Install the IS220PSVOH1A within the designated GE Mark VIe IO Pack mounting location.
- Verify that the 28 VDC supply wiring matches the system power distribution requirements before energizing the module.
- Route servo signal wiring separately from high-current power cables to reduce electrical interference.
- Use appropriate shielded cables for LVDT and actuator feedback connections.
- Connect cable shields according to the site grounding standard to minimize signal noise.
- Confirm Ethernet cable installation follows industrial network wiring practices before system commissioning.
- Check module status indicators after installation to verify normal startup operation.
