RFHSS Synthetic Fiber Humidity Controller

This device automatically detects relative humidity and directly activates load equipment such as dehumidifiers or heaters to prevent condensation inside enclosures. It is preset to Normally Open (NO) mode for dehumidification; when the humidity level rises, the contact closes to trigger the equipment. It supports a wide input voltage range of 24–230V and allows for humidity setting adjustments in 5% increments. The device is CE and UL certified for safety and compliance.

Product Features

With a settable relative humidity range of 40–90% and a switching differential of 5% RH, this device features a three-pole screw terminal block for AWG 20–14 (0.5–2.5mm²) wiring and a molded housing designed for installation on standard 35mm DIN rails according to EN 60715.
