The DRF series DIN rail signal conditioners are
designed to accept a broad range of input signals,
such as ac and dc voltage and current, frequency,
temperature (thermocouple and RTD), and process
transducers, and provide standard process outputs
of either 4 to 20 mA, or 0 to 10 Vdc. The DRF series
feature a modern housing design, that is easily
mounted on standard 35 mm DIN rails. Connections
are safely and securely made through pluggable
screw terminal connectors, with input and output
connections on the opposite sides of the module.
The DRF-RES and DRF-POT signal
conditioners accept resistance and
potentiometer input respectively and
provide an isolated 0 to 10 Vdc or
4 to 20 mA output.
The DRF-RES is available with four
standard ranges from 0 to 1500Ω
to 0 to 10,000Ω. The DRF-POT can
work with a variety of
potentiometers from 100Ω up
to 1 MΩ.
Models are available with three
different power options, 24 Vdc,
120 Vac and 240 Vac.
The DRF-RES and DRF-POT
are ideally suited for industrial
applications. All models mount on a
standard 35 mm DIN rail and
provide galvanic isolation between
input, output and power up to
3500 Veff (model specific). Module
response time is 70 ms or less.
