Dimensions 32 x 74 mm are miniature temperature controllers for medium temperature shutdown defrost refrigeration systems, It has 2 relay outputs: one is compressor (refrigeration) output, the other can be light, alarm signal number or auxiliary output, etc. There are 2 NTC or PTC probe inputs: one is for the library/cabinet temperature, and the other is for the temperature probe (P4) The input is optional, it needs to be specified when ordering, you can choose whether to use it through parameters, connect it to the 5-pin On terminals 2 and 4 (either left or right) of the hotkey programming key interface (connectors are required and must be ordered separately) goods, model: NG6-K), can be used to measure the condensation temperature alarm or to display the temperature at a certain point; digital enter The terminal can also be set as a third temperature probe (P3) input (use or not can be selected by parameter). The hot key programming interface can be connected to the programming key, and can also be connected to the XJ485-CX communication conversion module. Go to a network compatible with ModBUS-RTU protocol, 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).
