The AC-D-4M Large Display Event Counter features bright 2.3 inch LEDs that can be viewed up to 100 feet away. The counter can receive pulse inputs from Hall Effect sensors, photo-electric sensors, proximity sensors, encoders, or contact closures. One pulse input increments the display one count. A 12 VDC transducer power supply is available on the back terminal strip of the counter. Input rates are 300 Hz for sensors and encoders, and 30 Hz for contact closures. The AC-D-4M has the ability to be reset on the terminal strip by wiring a momentary contact closure.
