Electro-pneumatic Converter – IOEPC

The IOEPC is an electric-to-pneumatic transducer which converts an analogue input signal to a proportional pneumatic output. The unit will automatically modulate its control valve to regulate the branch-line pressure to the selected set point, as determined by the input signal. The unit offers four selectable input ranges: 0 to 5 VDC, 0 to 10 VDC, 0 to 15 VDC, and 0 to 20 mA. Output pressure ranges are jumper-shunt selectable to 0 to 10, 0 to 15, and 0 to 20 psig, and are adjustable in all ranges. A 0-5 VDC feedback signal indicating the resultant branch line pressure is also provided. This signal varies linearly with the selected branch pressure range. EPCs are designed with electrical terminals on one end and pneumatic connections on the other, allowing maximum convenience for wiring and tubing installation when panel-mounted.
