ACI Interface Devices: Solving Problems While Saving You Time and Money! ACI manufactures an extensive line of Interface Devices designed to solve problems. Many of our interface products are used to convert one signal type to another saving you time and money on retrofit projects. Two such devices are our A/EPC and A/PXP which convert analog signals to pressure outputs.
They are perfect for retrofit jobs with dampers or other parts controlled with pneumatic signals. Watch Tech-Tip Video on our A/PXP products.
