RS-485 interface with local and remote communication function, monitoring software RS-485/RS-232 convertor, one COM interface and one USB interface occupying PC computer; connect 16 sets of equipment at most; and the maximum accumulated length of the cable is 800M .
Anti-integration saturation PID
Curve recording function
RAM with battery protection it can save the setting value sampling value and sampling time of equipment; and the maximum recording time is 350 days (when the sampling period is 1.5 min)
It is equipped with one U -disk and software disk special for PC computer (applicable for complex Chinese, English WINDOWS operation system); the test program is compiled by PC special software and saved in U -disk; and then the test program is tuned out from the U -disk and saved in the controller; or the program in the controller is saved in U-disk and then it is saved in PC machine to be analyzed and managed. The test curve data saved in the controller can be saved in U- disk. The test data/ curve is directly printed and displayed by PC special software; or the recorded data is converted to Access data file read by Microsoft Office. The test curve data recorded by the recorder is as follows: two- circuit temperature– setting temperature and actual temperature; two- circuit humidity– setting humidity and actual humidity ( if the equipment has humidity function );record the time .
Fault alarm and reason, treatment prompt function, power failure protection function, and upper and lower temperature limit protection function; calendar timing function (automatic starting or automatic stopping); self-diagnostic function
Equipped with multi-level filter reverse osmosis water purifier (users provide tap water) or users provide humidification water with resistance rate ≥500Ωm
Cooling circulating water
Water supply pressure: 0.32~0.45MPa; water temperature: ≤30℃
20KW~55KW (it is different according to different models and configurations)
Observation window, wire hole, floodlight, time accumulator, one power wire (6m long), one sample power control terminal, one RS-485/232 interface, one USB and one U-disk;
Refrigerating system: over-voltage of compressor, over-heating of compressor, over-current of compressor motor, water supply and under-voltage of cooling water (water cooling); humidifying system (SQW model): dry burning of heating tube, abnormal water supply and abnormal water drainage. Test chamber: over-temperature protection, temperature fuse wire, over-heating of fan and motor, others: phase sequence of total power and lacking protection, leakage protection and load short circuit protection
