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-IDC and the DRF-IAC
current signal conditioners accept
dc and ac currents respectively
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-IDC and DRF-IAC
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).
