smart DIN rail lightening-protection temperature transmitter of thermal resistor
SPD function
Output signal range: 4~20mA..
R7S Series lightening-protection thermal resistor temperature transmitter, used for industrial automation system, receive on-site thermal resistor signal input, convert it to analog signal output with the same proportion and corresponding temperature, then isolate and transfer to DCS/PLC, which finally realize the temperature gathering and transmitting in industrial field, meanwhile meet with signal types matching, isolation, interference rejection and improve the system stability function between DCS/PLC.
Products of this series characteristically have SPD function, which can efficiently absorb and release the surge energy produced by (external) input induction lightening. Moreover, the three ends (input, output, power) of this series are completely isolated. It contains a variety of combination forms like one-input & one-output, one-input & two-output, two-input & two-output, etc. Width of the shell is only 12mm, which can satisfy the high-density requirements of on-site installation.
