Description
The Dwyer IP-42 is a precision current-to-pressure transducer engineered to convert a standard 4 to 20 mA electronic control signal into a proportional 3 to 15 PSI pneumatic output. This device serves as a critical interface between electronic building automation systems and pneumatic actuators, dampers, and valves — making it an ideal solution for retrofit and hybrid control applications in commercial HVAC systems.
Signal Conversion
The IP-42 accepts a 4 to 20 mA input signal and delivers a linear, proportional 3 to 15 PSI pneumatic output, ensuring accurate and repeatable control response across the full operating range.
