Combination of power supply &
six channel command voltage generator

DESCRIPTION
The SELECT 6 is designed to provide electrical
power and six selectable 0-10 vdc command voltages to
Proportion Air's electro-pneumatic control valves. This
product is very useful where up to six pressure set points
are needed and no analog signal is available to command
Proportion Air's control valves.
The SELECT 6 is a combination power supply and
six channel command voltage generator. The power supply portion will deliver a regulated 15 vdc at 600 mA.
The command generator is designed to accept an enable
signal from a PLC or other controller and output a preset command voltage. The enable signals are completely
isolated from the rest of the signal circuitry and power
supply with an opto-coupler, however they share a common return line. There are six selectable 0-10 vdc channels. The output voltage for each channel is user
settable by adjusting the corresponding potentiometer.
The SELECT 6 also includes a master gain potentiometer which sets the maximum output voltage for all
six of the selectable channels. The master gain potentiometer can be used to limit the maximum command
signal that a Proportion Air servo valve receives.
The SELECT 6 can be configured to accept input
power of 220 VAC, 110VAC, or 24 VDC. The enable
lines can be configured to accept 12VDC, 24VDC, or
110VAC. All the enable lines must accept the same voltage as they share a common return wire.
The Select 6 can be configured with remote potentiometers such that each channel output voltage can be
adjusted from a remote location.

(1) Select when Ordering.
(2) Tested at 2500 Vdc between select line and signal circuitry with less than 1 uA leakage.
NOTE:
Controllers utilizing TRIAC outputs to enable the select lines generally
have a small amount of leakage current through the TRIAC resulting in
the select line being enabled at all times. Controlling elements such as
switches and relays work the best.
