Dimensions 32 x 74 x 60 mm are suitable for micro temperature control of 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 one of lighting, alarm relay output, and auxiliary output; it can provide up to four One NTC or PTC probe input: one for the room temperature, one for the evaporator temperature (defrost termination temperature + fan stop temperature control), a settable passive digital switch input can also be connected to a third temperature probe input (for Optional, it needs to be specified when ordering; whether to use it can be selected by parameters); the fourth probe input (can also be used through (select whether to use or not through parameters), connect to No. 2 and No. 4 of the 5-pin hot key programming key interface (both left and right). Yes) on the terminal (requires plug-in converter), which can be used to measure the condensation temperature alarm or to display a certain point temperature; the hot key programming interface can be connected to the programming key, and can also be connected to the XJ485-CX communication conversion module Access to the 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).
