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-RTD RTD signal
conditioners accept 2 or 3 wire
100 platinum RTDs as input and
provide an isolated 0 to 10 Vdc
or 4 to 20 mA output. Models are
available with three different power
options,
24 Vdc, 120 Vac and
240 Vac.
The DRF-RTD 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 250 mS
or less.
