Communication function RS-485/232 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
Control mode 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 1.5min)
USB function 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 Accedd 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.
Auxiliary function Fault alarm and reason, treatment prompt function, power failure protection function, and upper and lower temperature limit protection; calendar timing function(automatic starting or automatic stopping); self-diagnostic function
