This model includes both a underspeed motion detector and a noncontact solid state proximity sensor. The output energizes for a set timer interval when it receives one control pulse from the proximity sensor. The output will remain energized as long as there are at least two pulses within the set time interval. The motion detector portion, the 1217C, can be ordered separately for use a PLC watchdog timer. It is also avalable with a 24VAC/DC power supply for this application.

Non-contact self-contained motion detector and proximity sensor in a limit switch style enclosure. Device is 2 wire, operates from 20 to 250 VAC/DC, switching 500 mA and is PLC compatable. A plug-in style connector simplifies installation. Three user selectable ranges cover from 5 to 5000 pulses per minute and an adjustable start time delay of 0 to 20 seconds is provided. Sensing distance is 1/2" with a 40mm x 40mm mild steel target.

Output energizes when speed is reached and stays so until unit receives less than 2 pulses in the time set. Time settings are available from .02 to 1000 sec., in 13 ranges, and operates on 120VAC. Initial start delays of 1, 5, 10, or 25 secs are available. Outputs include; 1 N.O. /1 N.C., 2 N.O., 2 N.C. relays. Input pulses can be provided by AC control circuit compatible with standard mechanical switches, solid state proximity sensors, and 120VAC pulse, or DC control circuit compatible with solid state source or sink proximity sensors.
