Dimensions 32 x 74 x 60 mm for micro temperature control for medium/low temperature forced air cooling system a compressor with four outputs: one compressor, one evaporator fan and one defrost (electric or hot gas), and One channel can be defined for lighting, alarm relay output, multi-function output and other functions; can provide built-in real-time Clock (RTC), which can be used to set defrost schedules up to 6 times per day, and can be divided into working days and holidays 2 different settings for the day; using the RTC also enables the use of different set points during the day and night to achieve Can run function; can provide up to four NTC or PT1000 probe inputs: one for room temperature, one for steam generator temperature (defrost termination temperature + fan stop temperature control), two programmable passive digital switch inputs The first channel (D.I.1) can also be connected to the third channel temperature probe input (it is optional, it needs to be specified when ordering; it can be Select whether to use through parameters); the fourth probe input (can also select whether to use through parameters), connect On terminals 2 and 4 (either left or right) of the 5-pin hotkey programming key interface (requires plug-in conversion controller), which can be used to measure the condensation temperature alarm or to display the temperature at a certain point; the hotkey programming interface (HOT Key) can be connected to the programming key, and the controller with TTL interface can also be connected to the XJ485-CX communication conversion module. The module or the controller with its own RS485 communication interface can be connected to the network compatible with the ModBUS-RTU protocol For example, DIXELL's XWEB series monitoring system, the form of communication port should be specified when ordering. The parameters can be quickly copied through the keyboard setting on the panel or the programming key (HOT KEY).
