Dimensions 32 x 74 x 60 mm are miniature temperature controllers suitable for medium temperature refrigeration systems, with 2 output Out: one way to control the compressor (refrigeration), the other way can be defined for lighting, alarm relay, defrost (electricity) hot or hot air) or a multi-function relay output; a built-in real-time clock is available (RTC), which can be used to set a defrost schedule up to 6 times per day, and can be divided into working days and holidays 2 Different sets of settings; using the RTC also enables the use of different set points during the day and night for energy efficient operation Line function; can provide up to four NTC or PT1000 probe inputs: one for library/cabinet temperature, one for steam generator temperature (defrost termination temperature control), one of the two programmable passive digital switch inputs (D.I.1) It can also be connected to the third temperature probe input (optional, it needs to be specified when ordering, it can be selected by parameter No use); the fourth probe input (can also be used through parameters), connected to the 5-pin hot key program On terminals 2 and 4 (numbered from the left or right) of the key interface (connectors are required and must be ordered separately, type No.: NG6-K), it can be used to measure the condensation temperature alarm or to display the temperature of a certain point; The port can be connected to the programming key, and can also be connected to the XJ485-CX communication conversion module to access the network compatible with the ModBUSRTU 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).
