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).
