Morningstar Relay Driver
TriStar
Manufacturer Part Number: RD-1
Morningstar’s Relay Driver (RD-1) is a logic module which provides high level system control functions such as high/low
voltage alarms, load control and generator start. The product controls four independent relay driver outputs by
reading digital data inputs from Morningstar’s TriStar controller or by reading battery voltage when used in systems
with other controllers.

Detailed Description
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.
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.
