PL70 Motion Monitors
The PL70 Motion Monitor is a microprocessor controlled speed monitoring device, sensing not only underspeed status but
also overspeed and zero speed. The PL70 is comprised of four parts: controller, sensor, target, cam and mounting bracket. A
standard NPN or other proximity type sensor compatible with the PL70 can be utilized; these sensors emit a serial of pulses
representing speed. The PL70 Controller has two DPDT contact alarm outputs and an optional 4~20mA output so that
programmed output functions can be made to monitor the equipment conditions.
