Failure is typically indicated by a persistent air leak (audible hiss) at the actuator housing or the actuator failing to reach its full stroke even when sufficient pneumatic control pressure is applied

The hardware itself is a passive resistive device

Broad Application: Ideal for chilled or hot water systems

maintaining all electrical and mechanical specifications

Advanced Diagnostics: Integrated LED flash codes allow for rapid fault retrieval of the last 5 stored errors

Johnson Controls DP1402X5U11D Pressure Transducer 321894-709 Failure is typically indicated byThe Johnson Controls DP1402X5U11D Pressure Transducer is a precision engineered low differential pressure transmitter designed for critical HVAC air monitoring and building automation. This unit features a 0 2. 5" wc pressure range and provides a stable 0 5Vdc output signal, making it a reliable choice for monitoring static or differential pressure in air handling systems. Built with a high performance capacitive sensing element, it maintains 0. 5%
