Description
GE IS220PDIOH1A
- Technical Specifications:
- Series: GE Mark VIe
- Inputs: Up to 24 contact inputs
- Outputs: Up to 12 relay outputs with feedback
- Connectivity: DC-62 connector to terminal board; two RJ45 Ethernet ports; three-pin power input
- Compatibility: Used with TDBS (simplex) and TDBT (TMR) terminal boards
- Environment: 0 °C to 60 °C operating temperature
- Functional Features:
- Combines discrete input and discrete output functions in one pack
- Supports TMR configurations when installed on TDBT terminal boards
- Features soft-start power-up to limit inrush current
- LED indicators for power, Ethernet link status, and relay status
- Application Scenarios:
- Turbine control systems requiring discrete I/O for solenoids, valves, and status contacts
- Discrete signal interfacing in distributed control systems
- Applications demanding redundancy and high availability
- Performance Parameters:
- Supports high-speed digital I/O with fast response times
- Isolated inputs up to 1500 V for noise immunity
- Material and Structural Characteristics:
- Industrial-grade PCB with potting or conformal coating
- Robust DC-62 and RJ45 connectors
- Designed for DIN-rack or panel-mount terminal boards
- Working Principle:
- Contact inputs are sensed and conditioned by the acquisition board; the processor board communicates the state to the Mark VIe controllers over Ethernet. Relay outputs are driven based on controller commands, with feedback monitored for fault detection.
- Installation Requirements:
- Secure the terminal board and connect the DC-62 connector without applying side loads
- Connect 24 VDC power; soft-start allows hot-swapping in many cases
- Connect Ethernet cables; ENET1 usually linked to the R controller network
- Use ToolboxST for configuration and diagnostics
- Usage Notes:
- Ensure terminal board compatibility (TDBS for simplex, TDBT for TMR)
- Avoid mechanical stress on the DC-62 connector
- Periodically check LEDs for status and fault indications
