About the RPS-409A-IS Sensor
The RPS-409A-IS is an intrinsically safe, analog ultrasonic self contained sensor in a 30mm PVC barrel style housing. It is powered by 16-30VDC with reverse polarity protection. It also has a narrow beam angle, which enables it to get into tight places. A flat target can tilt up to 10 degrees and still be detected.
The RPS-409A-IS has a short circuit protected analog 0-10VDC output. Example using the RPS-409A-80-IS: The output is a linear .125 volts per inch. Therefore a target placed 10 inches from the sensor will result in an output of 1.25 volts. Likewise a target placed 80 inches from the sensor will result in an output of 10 volts.
The RPS-409A-IS has built in temperature compensation to provide accurate readings throughout the entire operating temperature range.
An LED indicator is provided. The LED is green when not detecting and changes to red when a target moves into place. The sensor is completely sealed and the connection is made by way of IP and NEMA rated cables.
Besides the input and output lines there is a sync/enable line. This can be used for connecting multiple sensors together to prevent cross-talk, or to trigger the sensor at a particular time.
The RPS-409A-IS is designed to take advantage of today’s PLC and computer analog input cards. The numerical values that are programmed into the PLC or computer will determine the zero and span.
