The DRSL-RTD-LP RTD input non-isolated DIN rail loop-powered signal conditioner measures a standard 2-, 3- or 4-wire Pt100 temperature sensor and provides a passive analog current output signal. The DRSL-RTD-LP provides a competitive choice in terms of both price and technology for interfacing RTD signals to SCADA systems or PLC equipment. This unit is powered by the host (output) current signal loop. Low power consumption facilitates DIN rail mounting without the need for any air gap. Easy configuration of more than 1000 factory calibrated measurement ranges is done via DIP-switches. The unit operates over a wide temperature range from -25 to 70°C (-13 to 158°F).

I am using a 120 ohm resistor as a test input and getting 3.5mA output. PT100 resistance range is 100 to 138 ohms for 0 to 100C. Switch settings I have for DIP 1, 1 to 10 are off, on, off, on, off, off, on, off, on, on. Appreciate your help.
Thank you for your inquiry. That switch configuration tells us it is set up for 3 wire RTD and 4-20mA output. 138 ohms simulate 97 degrees C. Assuming all the wiring was done properly, 3.5mA out could still be correct depending on the settings you have for temperature range. Please contact our Data Acquisition group for more details on your specific case at das@omega.com.
