Description

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 series high performance lightning and surge protectors provide

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.

The compact weather resistant housing features a lockable hinged cover and break-away holes are provided on

the rear of the enclosure for mounting. The cable grommet may be adjusted to cable size and are removable.
