Relay Modules
The ML controller is supplied in two parts, a panel mount display / control unit and a relay / power supply module in a black ABS
enclosure. The two units are interconnected using the 5m lead supplied, the control unit derives it’s power from the relay module. All the
terminals for power, control relays, networking and temperature probes are contained within the relay module as shown below.
The ML controller can be used with a 230 Vac 50Hz or 110V 60Hz mains supply, the switched mains outputs for the relays are fed by the
relay module so only one mains supply needs to be connected.
