Product Information
5 UPC20+ Universal Power Controller
Power Control mode
The tables below specify the DIP switch settings for momentary, latching, 2-button On/Off, and
(momentary or latching) operation of K1 and K2.
Remote Sensor Control mode
The UPC20+ can also be controlled via the serial output from an AMX IR sensor. Remote sensor mode
is selected by setting jumper JP1 to the "Remote" position (jumper on the left 2 pins), as shown in
FIG. 3. (The jumper must be in position when power is applied to the UPC20+).
When controlled by a remote sensor, the UPC20+ is in 2, 3-button timer motor control mode. When the
timing potentiometer R8 adjusted to zero ohms (no time delay), the remote sensor provides momentary
control.
A 3-bit code (radio code) set on DIP switch S2 associates an AMX handheld remote control with a
UPC20+. This allows up to 8 UPC20+ and IR sensors to be used in the same room without interfering
with one another. It is possible to control 2 separate UPC20+'s with one handheld remote control. The
4th switch of DIP switch S2 on the PCB selects between the two UPC20+'s. The table below lists the
results of the 16 possible DIP switch selections in remote sensor mode.

If motors of any kind are used, do not set to a Power Control mode. When a Power
Control mode is selected, both relays can be on at the same time. Motors can be
severely damaged if this happens.
