Relay Driver Performs Functions Similar To Auxiliary Port

Morningstar offers a Relay Driver (model # RD-1) which can be used for many of the same functions as an auxiliary (IN or OUT). Each RD-1 has 4 channels that can be used as inputs or outputs for  Low Voltage Disconnect, Vent Fan, Alarm notifications, or Genstart. Output Channels can be turned on or off based on standalone relay driver values or information from other Morningstar devices on a MeterBus network such as:
  • Thresholds (Voltage, Current, Temperature, % PWM Duty Cycle)
  • Selected Alarms and/or Faults
  • PC or MODBUS inputs over the RS-232 Serial data connection
Advanced options allow users to use use the relay as a timer switch or to custom program delays.
