ACI PXP100 Sensor Interface Device (DISCONTINUED ITEM)

The PXP100 is an electric to pneumatic transducer which converts an analog electrical input signal to a proportional pneumatic output. The PXP100 will automatically modulate its control valves to regulate the branch line pressure to the selected set point as determined by the input signal. The PXP100 offers four selectable input ranges of 0 to 5, 0 to 10, 0 to 15 VDC and 0-20 mA that produce a 0 to 100 psig modulating output. A 0-5 VDC feedback signal indicating the resultant branch line pressure, is also provided. This signal varies linearly with branch pressure (0 volts = 0 psig, 5 volts = 100 psig/689.5 kPa). The PXP100 incorporates two valves and does not use air at set point. It’s branch exhaust flow and response time are not limited by an internal restrictor and are similar to its load rate. If power fails to the PXP100, branch line pressure remains constant as long as the branch line does not leak air.
