Relay Driver

The Relay Driver™ is a 4 channel logic module which provides high-level system control functions such as load control, generator start and alarm signaling. The four channels can be utilized as analog inputs or as relay driver outputs. The Relay Driver can operate in stand-alone mode or by reading meterbus data from other Morningstar products and it can be set up for advanced functionality with MSview.

Relay Driver Features

  • 4 channels: Each configurable as an Analog Input or Relay Driver Output
  • Standalone operation for battery or analog input voltage control or temperature control.
  • Expandable: Use 2 units and read and react on the others data
  • Reads MeterBusTM data from supported Morningstar controllers, inverters or Relay Drivers for logic control
  • Monitor battery and channel voltages, faults and alarms and ambient temperature 
  • Control Relay Driver outputs directly by Modbus commands via RS-232 for use with PLC’s and other industrial hardware.
  • Multiwire Generator Start/ Stop Control
