AC Power Detection Relay

The Furman Sound PS-REL detects AC voltage presence and automatically closes its output contacts. It is designed for installers who need to trigger downstream power sequencers or distribution units when a master outlet becomes live.

Contact Closure Trigger

The relay activates only when it senses AC power on its input, providing a hardwired contact closure to a terminal strip. This single sensing mechanism determines whether the unit will integrate with your existing Furman sequencing chain.

Terminal Strip Wiring

Connections are made to a terminal strip using standard low-voltage wire; no special tools are required beyond a screwdriver. The main installation error is reversing the sense and load circuits, which prevents the sequencer from receiving the trigger signal.

Questions about this item

What does the 52.5-inch height mean for rack mounting?

The unit stands 52.5 inches tall, so verify your rack or cabinet has at least that much clear vertical space before installation.

How does the AC-sensing relay interface work in practice?

It detects AC voltage on its input, then closes the internal relay contacts wired to the terminal strip, letting you trigger a Furman sequencer or PowerPort system automatically.

What physical clearance do the 30-inch width and 12-inch depth require?

Allow a mounting footprint of 30 inches wide by 12 inches deep, plus enough rear access for the terminal-strip wiring connections.
