Outdoor 4-Channel 4-20 mA Current Loop Protector - 12V

High voltage transients caused by lightning strikes have the ability to easily destroy semiconductor junctions, and thus, cause equipment failure and loss. A lightning strike close to data lines can also cause induced ground currents that can also do serious damage. The AL-CL4-12 high performance lightning and surge protector provides superior protection of for up to four 4-20 mA circuits against these transients or surges.

The low capacitance diode array assures that the signals will not be degraded by the suppressor. This is in comparison to protectors based on high capacitance TVS diodes. For more complete protection, two units should be used, one on each end of the line.
