RELAY MODULE and PLC

Here we are discussing the directions for the installation of your relay module. This relay module is UL Listed as an adjunct to be used solely with USI electrical and UNIVERSAL smoke alarms and warmth alarms and is employed to activate auxiliary devices. All devices to be activated should be one hundred twenty vacations, sixty rates five Amps most, or twenty-eight VDC five Amps most.
