The DRSL-RTD Series RTD input
DIN rail signal conditioners provide
a competitive choice in terms of both
price and technology for interfacing
RTD inputs to SCADA systems or
PLC equipment. The DRSL-RTD
and DRSL-RTD-ISO can be used for
signal conversion of 2, 3 or 4-wire
Pt100 RTD inputs into unipolar
analog signals. The DRSL-RTD-ISO
isolated model offers 3-way isolation
between input, output and supply
and provides surge suppression
and protects control systems from
transients and noise. 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).
