It also has a monitored switch input that is designed to supervise one or more normally-open switches connected to a single-pair of cables.
The device is supplied in a DIN-rail housing which can be clipped onto a standard 35 mm DIN-rail (DIN 46277). Connections are made via plug-in terminal blocks which accept wires up to 2.5 mm2.
The unit has dimensions of 110 x 107 x 20 mm and weighs 95g. It has been designed to comply with EN54–18.
The mains switching input/ output unit is loop-powered and can only operate with control equipment using the company’s XP95 or Discovery protocols.
Application examples include air sampling units, mains power shut-down on machinery, automatic door retainers, smoke dampers and gas valves.
