AC2-27
Universal Controller for DIN Rail
The AC2-27 is a universal controller with two independent outputs. You can select the operating mode (heating/cooling) for each channel in the menu, as well as whether you wish to control the channel with hysteresis or PID control!
For easy configuration, it is equipped with a guided 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 quickly adjusted to requirements using the L1 and L2 buttons. Naturally, the AC2-27 also features a Standby (I/O) button and an info menu.
