R7 series lightening-protection signal transmitter. used for industrial automation system. receive field signal input, convert it into analog signal output with the same proportion and corresponding temperature. then isolate and transfer to DCS/PLC. which finally realize signal gethering and transmitting for industrial filed, meanwhile it 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 input, output and power of this series are completely isolated, it has a variety of combination form like one-in one-out, one-in two-in two-out , etc...

width of the shell is only 12mm, which will satisty the high-density requirements of fileld installation.
