Working Principle
The ERB-112 receives control signals from a protection relay, PLC, or manual control circuit. When the input condition is satisfied, the internal relay changes its output state to energize or de-energize connected devices. The module monitors input signals and output status, providing feedback to the control system. If a fault or abnormal condition occurs, the relay can trigger an alarm, trip signal, or interlock action to protect downstream equipment.

Installation Requirements

  • Verify the correct model and system compatibility before installation.
  • Install in a dry, clean, and well-ventilated control panel.
  • Ensure the supply voltage matches the module nameplate rating.
  • Use proper wiring methods for control and load circuits.
  • Keep control wiring separated from high-power cables.
  • Tighten terminals to the recommended torque.
  • Confirm system configuration and protection settings before commissioning.

Precautions for Use

  • Do not exceed the rated input voltage or output load capacity.
  • Do not install the module in wet or corrosive environments.
  • Verify wiring polarity and terminal assignments before energizing.
  • Do not bypass protection or interlock functions.
  • Perform regular inspection of terminals, indicators, and mounting condition.
  • Replace failed modules with the same model and version.
  • Only qualified electrical personnel should install or maintain the device.
  • Refer to the official TERASAKI manual for exact electrical ratings.
