Overview

Details

DIN-Rail Mains Input/Output Unit

The DIN-Rail Mains Input/Output Unit provides a mains-rated voltage-free, single pole change-over relay output and a monitored switch input. The unit supervises one or more normally-open switches connected to a single pair of cables.

Electrical Description

The DIN-Rail Mains 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 DIN-Rail Mains Switching Input/Output Unit is supplied in a housing which is clipped onto a standard 35mm DIN-Rail (DIN 46277) using end stops, part number 27447–528 (which must be ordered separately).

Connections are made via plug in terminal blocks which accept wires up to 2.5mm2.

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.

If the indicating LEDs are not required or the extra loop current to illuminate them is not available, they can be disabled by using segment 8 of the DIL switch.

Device Addressing

The address of the Input/Output Unit is set using the lower seven segments of the DIL switch. Each segment of the switch must be set to “0” or “1”, using a small screwdriver or similar tool. For complete list of address settings refer to Installation Guide (39214-449).

Communication

The unit will operate only with control equipment using the Apollo XP95 or Discovery protocol.

EMC Directive 2014/30/EU

The DIN–Rail Mains Switching Input/Output Unit complies with the essential requirements of the EMC Directive 2014/30/EU, provided that it is used as described and that the contact is not operated more than five times a minute or twice in any two seconds.

A copy of the Declaration of Conformity is available from Apollo on request, or at www.apollo-fire.co.uk Conformity of the DIN–Rail Mains Switching Input/Output Unit with the EMC Directive does not confer compliance with the directive on any apparatus or systems connected to it.

Additional Information

ENCLOSURES

To meet EN54–18 requirements the DIN-Rail Mains Switching Input/Output Unit should be installed within a steel enclosure weighing greater than 4.75kg, available from electrical wholesalers and distributors.

For more information refer to Datasheet (PP2350) and Installation Guide (39214-449).
