<< | < | AX-EPC - Analogue to Pneumatic Converter
|
| |
|
The AX-EPC range is an analogue to pneumatic convertor which converts an analog input signal to a proportional pneumatic output, modulating its control valve(s) to regulate the branch line pressure to the set point determined by the input signal. Output pressure ranges are jumper shunt selectable for 0 to 10, 0 to 15 and 0 to 20 psig, and adjustable in all ranges. A 0-5 VDC feedback signal indicating the resultant branch line pressure, is also provided. AX-EPC’s are designed with electrical terminals on one end and pneumatic connections on the other, allowing for maximum convenience in wiring and tubing installation when panel mounted. |
