AC Relay Accessory

The PS-REL AC Relay provides an alternate way of closing switch contacts with trigger based AC power sensing.


Instead of being operated manually like the RS-1, PS-REL has a relay that detects the presence of AC power. In response, closes relay contacts that are wired to a terminal strip. It may be used with any of the Furman products mentioned in connection with the RS-1.

A PS-REL is useful in determining when a certain outlet has come on after a sequenced delay, to extend that outlet’s capacity. It may also be used to extend the capacity of the switched outlet found on many home theater receiver/amps. In this way, a wireless remote can turn on the receiver, which in turn powers its switched outlet, which triggers the PS-REL, which then activates a Furman PS-8R or PS-PRO Power Sequencer, MiniPort, or PowerPort system capable of switching many large power amps or other power-hungry equipment in multiple locations.


  • The PS-REL AC Relay Accessory is designed primarily for use with the PS-8R 15 amp Power Sequencer, the PS-PRO 20 amp Power Sequencer, the PowerPort 20 amp Remote AC Controller, the MiniPort-30 Power Relay (30 amps), MiniPort-20 Power Relay (rated 20 amps), and the MiniPort-15 Power Relay (rated 15 amps).
  • The PS-REL is simply a small box containing a relay. It functions as a sensor which can close a switch in response to the presence of AC power.
  • The PS-REL is needed whenever a PS-8R, PS-PRO, PowerPort or MiniPort (or linked chain of PowerPorts or MiniPorts) must be turned on in response to energizing a switched outlet. This occurs frequently in “Home Theater” installations when a switched outlet on a preamp or receiver, (often activated by a wireless remote device), is to be used to power up a large amount of equipment. It allows multiple 15-amp and 20-amp circuits to be controlled from one device.
