 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).
