Intrinsically Safe LED Indicator Various Sensing Ranges Analog Voltage Output Temperature Compensation PVC Enclosure Wide Temperature Range Sync/Tx Input Line 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.
