Dimensions 32 x 74 x 60 mm are micro temperature controllers suitable for medium/low temperature refrigeration systems, with 2 channels Output: One compressor and one defrost (electric or hot gas), with three NTC or PTC probes Input: one is the storage temperature, one is the evaporator temperature (defrost termination temperature), and one can be set to the passive digital switch input. It can be connected to the third-channel temperature probe input (optional, it needs to be specified when ordering; you can choose whether to use); the fourth probe input (can also be used by parameter selection), connected to the 5-pin hot key programming On the 2nd and 4th (left or right number) terminals of the key interface (connectors are required, which must be ordered separately, model: NG6-K), which can be used to measure the condensation temperature alarm or to display the temperature at a certain point; the hotkey programming interface can In order to connect the programming key, you can also connect the XJ485-CX communication conversion module to connect to the compatible ModBUS-RTU protocol network, such as DIXELL's XWEB series monitoring system. The parameters can be quickly copied through the keyboard setting on the panel or the programming key (HOT KEY).
