Addressable line relay module A50E-2

The A50E-2 is an addressable relay providing single pole, volt free, change over contacts. The unit is intended for installation within the equipment to be switched, thereby offering
savings in installation costs when compared to long, auxiliary circuit, wiring runs out from the control panel.

Complying with EN54 Part 18, the relay can be located anywhere on the two core ZP loop and is designed for power up or shut down of building services, for example air conditioning plant, in fire conditions. The unit is ideal for the control of associated system equipment such as door release circuits, or the emergency shutdown of high risk services, for instance gas or oil supply valves in boiler rooms.
