Pneumatic – Electric Interface Modules When upgrading to electronic control, it makes sense to keep the end devices such as valve actuators and damper actuators –pneumatic powered, especially if the intention is to keep the compressor. Occasionally the application may call for the pneumatic pressures to be converted to electronic. What ever the application, contact us for the correct answer. |

The EPC* is an electric to pneumatic transducer 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. The EPC* offers four selectable input ranges of 0 to 5, 0 to 10, 0 to 15 VDC and 0 to 20 mA. Output pressure ranges are jumper shunt selectable for 0 to 10, 0 to 15 and 0 to 20 psig, and adjustable in all ranges. Available with or without gauge and multiple outputs. |

The EPW* converts a pulse, phase cut, or digital PWM signal into a proportional pneumatic signal ranging from 0 to 20 psig. The pneumatic output is proportional to the signal input, either direct or reverse acting. The EPW* has a manual override potentiometer to vary the pneumatic output and two LEDs, one to indicate power and one for signal status. Available with or without gauge and multiple outputs. |

Three models of the PTP accept either a 3 to 15, 3 to 30, or 0 to minus 7.5 psig pneumatic pressure input and convert it to one of four proportional analog output ranges of 1-5, 2-10, 3-15 VDC or 4-20 mA which are jumper shunt selectable. PTP is a positive current output device that is fully temperature compensated. Available models include feed back, manual and override. |

The PXP*.3 is an electric to pneumatic transducer which converts an analog electrical input signal to a proportional pneumatic output. The PXP*.3 will automatically modulate its control valve(s) to regulate the branch line pressure to the selected set point as determined by the input signal. Available models include feed back,manual and override. |
