Overview

The Furman PS-REL Power Relay is a purpose-built accessory designed to extend the automation capabilities of Furman power sequencing systems. When connected to a switched outlet on a compatible Furman unit such as the PS-8R, PS-PRO, Miniport, or Power Port, the PS-REL senses the presence of 120 VAC and responds by closing a single-pole, double-throw (SPDT) relay. This contact closure can then be used to trigger additional equipment, activate a second power sequencer, or control any device that responds to a dry-contact signal.

Because the PS-REL operates on a simple detect-and-close principle, it integrates cleanly into both professional audio racks and home entertainment systems. AV integrators commonly use it to chain multiple sequencers together or to automate the power-up of equipment that sits outside the reach of a single Furman unit's switched outlets. The relay's SPDT configuration provides wiring flexibility, supporting both normally open and normally closed circuits depending on the needs of the installation.

Frequently Asked Questions

What does the Furman PS-REL actually do?

It detects the presence of 120 VAC on its input and closes a single-pole, double-throw (SPDT) relay contact, allowing you to trigger downstream equipment or extend switched outlet capacity in a power sequencing system.

Which Furman products is the PS-REL compatible with?

It is designed to work with Furman's PS-8R, PS-PRO, Miniport, and Power Port systems, as well as any product that requires a contact closure in response to AC voltage.

Does the PS-REL condition or filter power?

No. The PS-REL is strictly a relay accessory that senses AC voltage and closes a contact. Power conditioning and surge protection are handled by the Furman unit it connects to.

Can the PS-REL be used outside of pro audio applications?

Yes. Because it simply provides a contact closure when AC is present, it can be used in home entertainment systems, AV installations, or any scenario where automated relay switching is needed.
