AC Relay Accessory

MODEL PS-REL (FOR USE WITH PS-8R, PS-PRO, POWERPORT AND MINIPORTS)

Instruction Sheet

About the PS-REL

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.

Connect C to “+12V”

PS-REL terminal strip

The PS-REL has a two-prong AC plug on a 6-foot cord to activate
the relay, and three terminals that connect to the relay contacts (Fig.

1). There is a common contact labeled (C), a normally open contact
(NO), and a normally closed contact (NC). It should be noted that
when connecting the PS-REL to any Furman sequenced power
product that (C) should be connected to the (+12V) terminal, and
that (NC) should be connected to the (REM) terminal.
When the relay opens, the device will turn on. Two wires should
be connected to the +12V and REM IN screw terminals of the
PS-8R, PS-PRO, PowerPort, or MiniPorts. The PS-REL’s AC cord
should be plugged into the outlet to be sensed.
The PS-REL AC Relay Accessory may also be used: (1) To
allow a PS-8R or PS-PRO to be hooked up to another PS-8R or
PS-PRO to provide six separate delayed turn on/turn off groups, by
having the relay sense the presence of power at the Delay 3 outlet,
(2) To turn on a single PowerPort or a chain of PowerPorts linked
together; (3) To turn on a MiniPort or a chain of MiniPorts linked
together.

Connect NC to “REMOTE”

When AC power appears at the sensed outlet, the PS-8R,
PS-PRO, PowerPort (or linked chain of PowerPorts), or MiniPort
(or linked chain of MiniPorts) will begin its turn-on sequence.
