Rear Lamp Socket
The PS-8RE III features a rear rack BNC socket
which will accept any 12 VDC or 12VAC up to ½ Amp
gooseneck lamp assembly, (such as the Furman GN-
LED or GN-I).
Remote Interface
The PS-8RE III has a remote interface which can be
used to control the PS-8RE III remotely using a Furman
RS-1 (Maintained) or RS-2 (Momentary) wall switches.
In the most basic, single unit configuration, only two
wires and a switch are required to initiate a remote ON
or OFF sequence. The switch may be either a momen-
tary or maintained-contact type. If a third & fourth wire
are available, an LED "Status Light" can be installed at
1
the remote switching location to indicate the status of the
PS-8RE III. The pins on the remote interface are de-
scribed below:

Output for driving an external

Common)
Simply slide the BNC plug over the socket and rotate
clockwise until both connectors snap into the locked
+
position. The rear rack lamp can be powered ON or
OFF with the Rear Lamp power switch which is lo-
-
cated on the far left side of the front panel.
Note that the rear lamp socket is powered by 12 Volts
DC and is therefore polarized. The lamp connector is
polarized center positive (Figure A). If you are using
a polarized lamp, please make sure that the lamp is
polarized center positive. Most LED and incandes-
cent lamps are polarity independent.
in "Legacy" mode by feeding the +12VDC signal back
into the REM terminal input; which is pin #3 on the same
connector.
PIN 2 STATUS (Output)
The STAT (status) terminal is an output that may be used
to activate an LED to indicate the status of the PS-8RE

III. If the STAT terminal is high, the PS-8RE III Delay out-
ON
lets are either ON, or are in the process of sequencing
ON. If the STAT terminal is low, the PS-8RE III Delay
outlets are OFF. To use the STAT terminal output simply
connect an LED between the STAT and GND with the
Cathode (flat) side of the LED oriented toward the GND
pin (Pin #4). Do not use a series current limiting resis-
tor. If the LED does not light when the remote switch is
12V 0.5A
ON, check the polarity of the LED and reverse the leads
if necessary.
• If the LED is OFF, the DELAY outputs are OFF
• If the LED is ON, the DELAY outputs are ON
• If the LED is blinking, the DELAY 1,2 or 3 outputs
are in transition either from ON to OFF or OFF to ON
PIN 3 REMOTE (Input)
The REM (remote) terminal is provided to allow remotely
connected devices to sequence the PS-8RE III ON or
OFF. The REM terminal has been designed to work with
voltages from 5 to 30VDC. Filtering has been added to
this input to prevent false triggering. The behavior of the
PS-8RE III is controlled by the combination of the signal
presented at the REM terminal input, and the arrange-
ment of the rear panel DIP switches. Please refer to DIP
SWITCH section for more details.
