The W351 Electronic On/Off Humidity Control is an electronic humidity control with SPDT relay output and LED indication. This control is used in conjunction with the HE‑67S3‑0N0BT or HE‑67S3‑0N00P series of humidity transmitters to stage humidification and dehumidification equipment. The control covers a range of 10 to 90% RH and has adjustments for setpoint, differential, and mode (humidification or dehumidification). The S351 Stage Module, D351 Display Module, and the Y350R Power Modules can be used with the W351.
