Relay Driver
Morningstar’s new Relay Driver provides high level
system control functions(such as high/low voltage alarms, load control and generator
start) at a lower cost than other alarm and generator start packages.
* One or more of Morningstar’s TriStar controllers coupled with the Relay Driver will control hundreds of amps at 12-48VDC with sophisticated features at a much lower cost than comparable large PV controllers. The Relay Driver will read the digital data inputs from the TriStar.
* In systems using other controllers, the Relay Driver will provide similar functionality based on battery voltage or input voltages from other sources.
* The Relay Driver controls four independent relay driver outputs for high/low alarm contacts, generator start functions, load control, temperature control settings and auxiliary AC backup charge control.
* The Relay Driver may be mounted to a DIN rail and is fully programmable with the included PC software via serial RS-232 port connection. Data is stored in non-volatile memory.
* In external slave mode, the Relay Driver can be controlled via the RS-232 serial connection by any MODBUS compatible device, local or remote.
* See Application Guide below in Multimedia section for specifics on how to use in various applications.

Works Like Expected but Needs Some Updating
The driver worked like expexted however couple things would make it better. It did not come with USB cable and most laptops do not have serial ports anymore. The other was the instructions did not have examples for using as alt-energy solution. I am using to turn on and off grid power to Xantex p...

Excellent tool!
This 4 channel processor works great.
Can control many relays as more relay can be connected
to each channel. Easily programmable via PC. Connects
via old serial RS 232 port. If Ur laptop does not have such
get a USB-serial converter cable. They are cheap. Brand Tripp-lite wor...

Exceeded my expectations
Calling this product a relay driver is, in my opinion, a mistake. The name implies that it simply amplifies a weak signal in order to power a relay. The device is much more than that. It should be called a programmable logic module, or perhaps a 4-channel programmable voltage controlled switch. P...
