Ziton A Series Mini Relay Unit, mains switching

A51E-1 - Addressable mains relay module

Rated to switch local mains - The Ziton A51E is an addressable relay providing double pole, volt free, change over contacts, rated to switch local mains supplies. The Ziton A51E 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 Ziton A51E relay can be located anywhere on the two core ZP loop and is designed for power up or shut down of the mains electrical supply to ancillary equipment The Ziton A51E unit is ideal for the control of associated system equipment such as mains fed magnetic door release circuits, extract fans and dampers.

Low profile moulding - The Ziton A51E relay can be programmed to be activated by any single device, groups of devices or all system devices. All types of system input signals can be arranged to operate the Ziton A51E, which can include control panel indicators, zonal outputs, callpoints or sensors. Terminals 1-2 and 5-6 provide normally closed relay connections (opening on alarm), terminals 2-3 and 4-5 provide normally open relay connections (closing on alarm).

Housed in a low profile moulding, the relay is designed to clip directly onto a standard DIN 35 mounting rail or equipment panel chassis. Alternatively the relay can be installed in a SMB-DIN100 box (one unit capacity) or SMB-DIN200 box (two unit capacity) care should be taken to prohibit casual entry into the enclosure.

LED indication - A red LED indicator positioned on the front moulding flashes when the interface contacts have operated. For system test and commissioning the relay contacts can be operated manually, enabling control circuits to be tested. Installed as part of an analogue addressable system, up to 127 line devices (sensors, callpoints or interface units) can be connected to each of the control panel loops. All loop devices incorporate switch settings enabling them to be assigned a unique address, which is polled by the panel every two seconds.
