    Morningstar Relay Driver
    The Morningstar Relay Driver is a logic module that provides control functions such as high/low-voltage alarms, load control, and generator start functions for 12, 24 or 48 VDC battery systems. It controls four independent relay driver outputs by reading battery voltage or by digital data inputs from any Morningstar controller or inverter, which includes an RJ-11 meter port (TriStar, TriStar MPPT, SunSaver Duo, SunSaver MPPT or SureSine). Multiple Relay Drivers can connect to a single controller or to multiple devices in a MeterHUB/MeterBus network. Outputs can be used to operate any mechanical or solid-state relay with a coil voltage that is the same as the battery voltage used to power the Relay Driver. Maximum current for each output channel is 750 mA.

    The Relay Driver is pre-programmed with four commonly-used settings and may be mounted to a DIN rail or a flat surface. An RS-232 port and PC software (MS View or MODBUS commands) is included for custom programming, detailed monitoring and driver control. The driver terminals can accept 16 or 24 AWG wire. Self-consumption is less than 20 mA and the unit operates from 8 to 68 VDC. The Relay Driver is highly reliable: each channel has complete electronic protections for short circuit, overcurrent, reverse polarity, as well as lightning and transient surges. LED indicators display power and status for each channel as well as faults and data sampling intervals. Operating temperature range is -40 °C to +45 °C. Dimensions are 6.4"H x 3.2"W x 1.3"D and it weighs 0.4 lb. These are covered by a 5-year warranty.

    Typical Functions
  • High and Low Alarm Contacts for Industrial Applications
  • Load Control Including High Power Applications (pumps and large motors)
  • Temperature Controlled Settings for Battery Fans or Cooling Vents
  • Generator Start Functions
  • Auxiliary AC Backup Charge Control

    Data Control Input Options

  • Connected to a TriStar Controller: Battery voltage, charge/load current, battery temperature, TriStar heatsink temperature, PWM duty cycle, PV/load voltage, and all TriStar alarms or faults
  • Used in Systems with Other Controllers: Battery voltage, Relay Driver temperature, input voltages from other sources.

    Features

  • Cost Effective: The four channels provide up to four high level system control functions at a lower cost compared to other alarm and generator start packages.
  • High Reliability: Each channel has complete electronic protections for high reliability
  • Flexibility: The system designer may choose the exact relay needed for each application including a wide range of current ratings and solid state, mechanical or mercury displacement relays.
  • Fully Programmable: It is easy to program the Relay Driver with the included PC software via serial RS-232 port connection. Data is stored in non-volatile memory. The Relay Driver is pre-programmed with four commonly used settings.
  • Advanced Generator Control: Provides flexible parameters to control one, two or three-wire generator schemes and complete control of preheat, crank, ignition and cool-down.
  • Industrial Design: Each relay driver output may be controlled directly by MODBUS commands via the RS-232 for use with PLC’s and other industrial hardware. Mounts to a DIN rail or a flat surface.
  • LED Indicators: Displays power and status of each channel as well as faults and data sampling intervals.
