AC1-27A

Hygrostat for DIN rail

The AC1-27 is a universal humidistat with two independent outputs. You can select the operating mode (humidification/dehumidification) for each channel in the menu, as well as whether you want to control the channel with hysteresis or with PID control! For easy parameterization, it is equipped with a supported parameter programming system so that only the parameters required for the specifically selected application are displayed. This makes programming the controller faster and more efficient. The two setpoints can be adjusted to requirements in a flash using the L1 and L2 buttons. Of course, the AC1-27 also has a standby (I/O) button and an info menu.
