Powering

The EIDX requires low-voltage AC or DC power via a four-pin removable keyed

connector. Power conductors can be stranded (16–18 AWG) or solid (16–22

AWG). Consult the Specifications section for power requirements. The various

power options are explained below.

NOTE:

This device is intended for use with Class 2 circuits.

DC Powered

The EIDX accepts a voltage of 24 VDC ±5% and draws current commensurate

with power consumption. Power conductors should be sized accordingly. COM

and the equipment chassis are isolated from zero volts. The input connections are

reverse-polarity protected.

Redundant DC Powered

Redundant diode-isolated DC power inputs are provided so the EIDX can operate

despite the loss of primary power. Both sources must provide required power.

AC Powered

The EIDX accepts a voltage of 24 VAC ±5% and draws current commensurate

with power consumption.

AC Powered with Battery Backup

The EIDX can also operate in the AC

mode with a backup battery providing

power if the AC source fails. The EIDX

does NOT charge the battery, so separate

provisions are required for charging.
