The Floscan Mains Interface Relay Module is a DIN rail/surface mounted unit that provides DC power for one or two Floscan sensors, from any mains power source. Each sensor output drives a relay in the module, allowing external signalling via the 8 Amp voltage free relay contacts. The two Floscan sensors can be high or low flow alarms (dictated by the sensor orientation) and can be on the same flowmeter tube or on separate flowmeters. LED indicators display energised relay normal conditions. The module can also be used to power and monitor alarm outputs from the Vampire GMTXD transmitter.
