SELECT 6 POWER SUPPLY & COMMAND GENERATOR ♦ 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.

(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.

SELECTABLE PRESSURE CONTROL POWER SUPPLY VOLTAGE A = 24VDC B = 110 VAC C = 220 VAC When ordering a Select 6, two items must be considered. POWER SUPPLY available and VOLTAGE. Power supply simply refers to the power available to operate the Select 6. The select voltage is determined by the supply available to activate the select lines. PROPORTION-AIR, INC.
