Kele RES-1E Universal Resistance Transducer – Analog to Resistance Converter (24VAC/VDC)

The Kele RES-1E Universal Resistance Transducer is a versatile signal conversion device designed to convert a wide range of analog or PWM input signals into precise resistance outputs. This DIN-rail mounted resistance converter is commonly used in building automation, HVAC control systems, and industrial applications where analog signals must be translated into resistance values to control equipment such as actuators, boilers, and chillers.

Engineered for flexibility and reliability, the RES-1E accepts multiple input signal types including 0–20 mA, 4–20 mA, 0–5 VDC, 1–5 VDC, 0–10 VDC, 2–10 VDC, 0–15 VDC, 3–15 VDC, and PWM signals. DIP-switch selectable configuration allows installers to easily adjust input types and output ranges, making this transducer an ideal solution for replacing motorized slide-wire potentiometer controllers or temperature sensors in reset circuits.

With multiple selectable resistance outputs including 0–135 Ω, 0–270 Ω, 0–500 Ω, and 0–1000 Ω, as well as custom ranges, the RES-1E offers exceptional compatibility across a wide variety of HVAC and automation systems. Its ±1% accuracy, LED status indication, and built-in failsafe and signal-loss features ensure dependable system control and monitoring.

Designed for simple installation, the unit mounts easily on DIN rail or snap-track and features screw terminal wiring for secure connections. The compact design and wide operating temperature range make it suitable for demanding control panel environments.
