The RPS-409A-IS3 is an intrinsically safe analog ultrasonic sensor available in a variety of ranges. The RPS-409A-IS3 sensors can be used in hazardous gas or dust environments classified as Class I, II, or III when used with approved intrinsic safety barrier(s). See the RPS-409A-IS3 User Manual and Control Drawing No. 14122606 for further information on installation in hazardous locations.
The sensor is self-contained in a 30mm barrel style enclosure, and is powered by 16 – 30 V dc with reverse polarity protection. The RPS-409A-IS3 has a short circuit protected 0 – 10 V dc analog output. The analog voltage is a fixed volts per inch based on the maximum range of the unit. For example when using the RPS-409A-80-IS3, the output is a linear 0.125 V per inch. A target placed 10 inches from the sensor will result in an output of 1.25 V, and a target placed 80 inches from the sensor will result in an output of 10 V.

The RPS-409A-IS3 has built-in temperature compensation to provide accurate readings throughout the entire operating temperature range.
An LED indicator is provided. The LED is green with no target detected and changes to red when a target is detected. The sensor is completely sealed and connection must be made with a cable having a rating of IP67 or greater.

In addition to the analog output line the sensor also has a Sync/Tx line. This line can be used for connecting multiple sensors together (Sync) to prevent cross talk, or (Tx) to control when the sensor transmits.

The RPS-409A-IS3 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 of the sensor.
