- AO5082 detection terminal thermal resistance input isolated safety barrier (one in one out, one in two out)
◆ Performance Overview
Isolate and convert the thermal resistance signal from the hazardous area into a current/voltage signal for output to the safe area. The input end, output end, and power supply end are three terminal isolated, with functions such as online fault self diagnosis, making it an intelligent safety barrier product. Optional use of our company's dedicated handheld programmer for parameter modification or calibration (see Programmer User Manual for details).
◆ Output status during input fault

Follow method: Unless otherwise specified by the user, regardless of the fault state of the input signal (open circuit, short circuit, reverse connection, over range), the output will follow the changes of the input signal within the full range, but the maximum value will not exceed 12.5% of the output range (for example, when outputting 4mA to 20mA, the small output can be 0mA and the large output cannot exceed 22mA).
