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-PR signal conditioner
accepts a dc process signal input
and provides 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-PR are ideally suited for industrial
applications. They feature galvanic isolation between input,
output and power up to 3500 Veff (model specific).
Module response time is 70 ms or less.
