550ACT Electro Pneumatic Transducer

Type EAA-550 series I/P,E/P transducer(Electro-pneumatic transducer,I/P,E/P converter) is an electronic pressure regulator that converts a variable signal (current or voltage) to a proportional pneumatic output.

Requirements for the use of this miniature electro pneumatic transducer

The 550X E/P transducer is a conversion instrument that can convert 4-20mA into a 20-100KPa pneumatic signal. 550X E/P transducer should be used according to the site conditions, that is, the spring compression coefficient of the pneumatic control valve connected to the E/P transducer is 20-100KPa, If 550X E/P transducer is used beyond this range, the full-open and full-close actions of the regulating valve cannot be realized. This is different from the valve positioner, and the electrical converter must be carefully selected.
