4.1 Programmable Relay Board
The Programmable Relay Board (PRB) provides a means to trigger an external device when an
event occurs in the Liebert
®
NXL
™
. Each PRB has eight channels. Each channel has Form-C dry
contacts rated at 1A @ 30VDC or 125VAC @ 0.45A.
Any alarm/event can be programmed to any channel or channels. Up to four (4) events can be
programmed to a relay. If multiple events are grouped to one relay, group the events logically to
simplify troubleshooting when an event is triggered. The same alarm/event can be programmed
to more than one channel. Up to two Programmable Relay Boards can be installed in the Liebert
®
NXL
™
for a total of 16 channels. Programming is performed through the HMI touchscreen display.

NOTE
Up to two (2) PRB’s can be installed in the Liebert® NXL™.
