Working Principle
The ESM-103B receives input signals from sensors, switches, protection relays, or external controllers. The onboard processor evaluates these signals according to configured logic, protection rules, or communication commands. It then generates output signals to control relays, breakers, alarms, or other devices. If communication interfaces are present, the module can exchange status data, setpoints, and fault information with上位机 systems, PLCs, or protection management units. When abnormal conditions are detected, the module triggers alarms, trips, or interlock actions to maintain system safety.

Installation Requirements

  • Confirm compatibility with the TERASAKI system before installation.
  • Power down the control rack before inserting or removing the module.
  • Handle the board by its edges to avoid damaging components.
  • Ensure connectors are clean and fully seated.
  • Verify system firmware and configuration compatibility.
  • Check indicator status after power-up.
  • Perform functional testing before placing the system into service.

Precautions for Use

  • Do not insert or remove the module while the system is energized unless permitted by the manual.
  • Avoid static discharge when handling the board.
  • Do not expose the module to moisture, dust, or corrosive gases.
  • Verify communication settings before connecting to external systems.
  • Do not modify firmware or parameters without authorization.
  • Keep a backup of configuration data before maintenance.
  • Replace faulty boards with the same model and version.
  • Only qualified engineers should configure or troubleshoot the module.
  • Refer to the official TERASAKI documentation for exact I/O definitions, communication protocols, and electrical ratings.
