UPC20+ Wiring Requirements
In the United States, the UPC20+ must be wired by an authorized electrician in
accordance with the National Electrical Code, ANSI/NFPA 70-1987, as well as all
local codes.
In the European community, the UPC20+ unit must be wired by an authorized elec-
trician in accordance with all applicable European codes.
A readily accessible disconnect device shall be incorporated into the fixed wiring.
An insulated earthing conductor that is identical in size, insulation material and

UPC20+ Universal Power Controller
Product Information
The UPC20+ Universal Power Control is a dual 20 Amp AC power and motor controller designed for
conduit installation. The UPC20+ is housed in a compact metal wall-mount enclosure and is
configurable for a wide variety of power and motor control modes. Low voltage contact-closures, open
collector inputs or serial data from an AMX IR receiver enable control by simple wall panels, remote
systems, or hand-held transmitters. A test switch with an LED indicator for each relay is provided for
local control and status indication.
Using Motor Control mode, the UPC20+ output alternates between two relays, providing a brief pause
in-between relay contacts, to protect the motor. A timing adjustment potentiometer is user adjustable for
automatic release of the relays. (The range is 0 to 90 seconds). 1-, 2-, and 3- button control modes are
selectable.
In Power Control mode, the UPC20+ provides power control for two independent circuits with a
combined total load of 20 Amps. Single-button momentary/latching and 2-button latching modes are
selectable.
 Momentary Power Relay contacts are closed only as long as a closure from input to
common is maintained.
 Latching Power Relay contacts are toggled (from open to closed and closed to open) each
time a closure from input to common is momentarily pulsed.
All functions and capabilities of the UPC20+ (including information on high voltage wiring, low voltage
wiring, and DIP switch settings) are described on a sticker installed inside the enclosure. FIG. 1 shows
the UPC20+ (inside view).
The UPC20+ will work the NXC-I/O10 input/output control card.

Control Options Modes
FIG. 2 UPC20+ inoperative mode warning label
Motor Control mode
The table list options and connections for motor control. DIP switch settings provide 1, 2 or 3 button
remote control contact arrangements. This mode is typically used for screen and drape motor control.
In motor control mode, only one power relay (motor) can be energized at a time. When switching from
one direction to another, the first motor is automatically turned off and a half-second delay is inserted
before the other motor will turn on.
Once a motor is turned on, it will automatically be turned off after the amount of time determined by the
motor time delay potentiometer, R8. Delay time can range from 0 to 90 seconds. It is typically set to
allow direction limit switches to operate, or to reach the desired position.
 Single Button Mode operates with one pushbutton in a sequence: Up, Stop, Down, Stop and
so on for each successive button press.
 Two/Three Button Mode operates with two pushbuttons, one for Up and one for Down.
 Momentary On/Off operates only when the button is pressed.
