Relay Card

The relay card provides voltage-free contact closures for remote monitoring of alarm conditions.

Delivering On Battery, On Bypass, Low Battery, Summary Alarm, UPS Fault and On UPS sig- nals, the easy-to-install card integrates with AS/400 computers (additional cable required) and other relay contact monitoring systems.

The relay card is rated for 24 VAC/DC at 1A and supported in any of the three Liebert IntelliSlot bays on the Liebert NX.
