  • Control Outputs: Drives alarms, indicators, and auxiliary relays.

Application Scenarios
Essential in gas turbine, steam turbine, and combined cycle power generation control systems.

Performance Parameters

  • Input Accuracy: ±0.1% for critical process variables.
  • Output Rating: Relay contacts rated for 2A at 250VAC.

Material Composition
Robust construction with isolated I/O channels, surge protection devices, and conformal-coated PCBs for harsh plant environments.

Structural Characteristics
Mark IV standard board size with front-panel terminal blocks and backplane edge connector. Includes test points for each I/O channel.

Operating Principle
Conditions field signals, converts them to digital format for the Mark IV processor, and translates processor commands into physical relay actions and analog outputs.

Installation Requirements
Install in correct Mark IV rack position. Wire field devices using shielded cable with proper grounding. Verify terminal assignments against wiring diagrams.

Usage Precautions
Never connect field power before verifying wiring. Use only specified fuse ratings. Perform I/O calibration after board replacement.
