MRX-20 ADVANCED NETWORK SYSTEM CONTROLLER
Wiring to the Relay on the MRX-20
The MRX-20 has a Relay with three contacts, NO, NC, and COM.
These can be used as dry contacts or to send a current to an electrical
switch or motor for use with screens, blinds, curtains, etc.
The Relay can be used as either a latching contact or a momentary
contact depending on the programming. The command to actuate the
Relay is programmed using the Accelerator software and is sent from
the MRX-20 when triggered by any Total Control system remote.
