DWYER IP-42 IP-43 IP-44 CURRENT TO PRESSURE TRANSDUCER Intrinsically Safe NEMA 4X Enclosure Field Reversible Low Cost
The SERIES IP Current to Pressure Transducer converts a current input signal to a linearly proportional pneumatic output pressure. The features include built-in volume booster, low air consumption, field reversible (provides output which is inversely proportional to input signal) and flexible zero and span adjustments. The rugged NEMA 4X enclosure allows splashdown and outdoor installation. The IP can be used for applications that require operation of valve actuators, pneumatic valve positioners, damper and louver actuators, final control elements and relays.
