Industrial TT7800-401 Electro-Pneumatic Transducer

Fairchild TT7800-401 Electro-Pneumatic Transducer is an industrial device that converts electrical control signals into a regulated pneumatic pressure output. The TT7800-401 model provides a 3–15 PSIG (pounds per square inch gauge) output, enabling proportional pneumatic actuation for automation systems that require modest air pressure. In practical terms, this transducer is used to drive pneumatic actuators, valves, and other control devices by translating an electrical input into a corresponding pneumatic pressure within the 3–15 PSIG range. Manufactured by Fairchild and identified by the TT7800-401 designation, it sits in the spectrum of electro-pneumatic transducers designed for process instrumentation and machine control loops. The key specification here is the selectable output pressure range of 3–15 PSIG, which defines the span of actuation available from the electrical signal. When integrating this part, ensure the control signal compatibility and that your pneumatic circuitry is designed to operate within the 3–15 PSIG window. This makes the TT7800-401 a fitting choice for low-pressure pneumatic control tasks in industrial environments where precise, electrical-to-pneumatic conversion is required.
