this single-stage SPDT control provides a wide regulation range from -40°F to 212°F
providing a robust safety margin over 370V alternatives in high-demand HVACR applications
it should be mounted to a boiler tap above the water level
designed to detect flammable vapors in the surrounding environment and prevent ignition
allowing for field-calibrated setpoints that optimize chiller efficiency and prevent low head pressure issues during low ambient operations
Kele Product RES-1E Transducer Freon this single-stage SPDT control providesThe Kele RES 1E Universal Resistance Transducer is the professional upgrade and direct replacement for the legacy RES 1, providing field hardened analog to resistance conversion for complex building automation systems. Designed for technicians requiring a reliable DIN rail mounted resistance converter, this unit translates standard 420 mA, 010 VDC, and PWM signals into precise resistance outputs to drive electric actuators, boilers, and chillers.
