AC powered model with relay output for stand-alone operation. Single channel system with manual and automatic operation. Two levels per each mode for individual range setting. Timer functions for on-delay, off-delay and pulse forming. Light/dark switchmode for inverted output signal. Two frequency settings allow close mounting of adjacent beams. Sensor alignment information and diagnostics are available at the touch of a button. The analog output makes sensor alignment easy and can also be used for simple measurement tasks.
