Interfaces for External Monitoring

Three interfaces are provided:

  • RS485 communication channel that can be programmed for Modbus RTU protocol
  • Relay output indicating real-time measured energy (configurable)
  • Pulse output 3200IMP/kWh (not configurable)

The Modbus configuration (baud rate etc.) and the pulse relay output assignments (kW/kVArh, import/export etc.) are configured through the set-up screens

SDM630 - Modbus (RS485 Output for Modbus RTU & Pulsed Output)

For Modbus RTU, the following RS485 communication parameters can be configured from the set-up menu:
