Transducers

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, eld reversible (provides output which is inversely proportional to input signal) and exible 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, nal control elements and relays.

FEATURES/BENEFITS

• Built-in volume booster

• Low air consumption

• Flexible zero plus span adjustments
