55000-875APO - Mains Switching Input/Output Unit
The Mains Switching Input/Output Unit provides a voltage-free, single pole change-over relay output and a monitored switch input.
Full Details
Electrical Description

The Mains Switching Input/Output Unit is loop powered and operates at 17–28V DC with protocol voltage pulses of 5–9V. The loop connections are polarity sensitive.

Mechanical Construction

The Mains Switching Input/Output Unit is supplied with a backbox for surface mounting and is intended for indoor use only. The backbox is moulded from the same white self-extinguishing polycarbonate as Apollo detectors. Three LEDs, two red and one yellow, are visible through the front cover of the enclosure. One red LED is illuminated to indicate that the relay is set. The second red LED is illuminated to indicate that the switch input is closed. The yellow LED is illuminated whenever a fault condition (open or short circuit) has been detected. All LED indicators can be disabled using segment 8 of the DIL switch. The enclosure is moulded from polycarbonate.

Backward Compatibility

XP95, Discovery & CoreProtocol compatible

Safety Note

Caution: The Mains Switching Input/Output Unit is not designed for outdoor use unless it is mounted in a suitable weatherproof enclosure. It is designed to switch mains voltages of up to 250V and should be installed with all due care by a qualified person. Isolate mains supply before starting work.
