The Furman PS-Rel is a AC Relay Accessory for use with sequencing units. Functions as a sensor which can close a switch in response to the presence of AC power remotely triggering other Furman sequencers.
The PS-REL AC Relay provides an alternate way of closing switch contacts. Instead of being operated manually like the RS-1, it is a relay that detects the presence of AC power and, 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.
