U Compatible with Standard 35 mm DIN Rail

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.

Functionality

The DRF series are designed to maximize
functionality. The front door of the housing provides
easy access to span and offset potentiometers
which may be used to field adjust the input and
output signal range.

Isolation

The input, output and power circuits are isolated by
3500 volts of galvanic isolation. The isolation protects
against potentially damaging voltages from passing
through the signal conditioners into connected
systems. The isolation also provides improved
measurement accuracy by minimizing the effects of
ground loops and electrical noise.

Outputs

Each DRF series signal conditioner is available with
current and voltage output (only one may be used at
a time). Available output types include 4 to 20 mA or
0 to 10 Vdc. Although pre-configured before shipping
from the factory, the output may be changed through
an internal jumper change.

Standard outputs are linear and proportional to the
signal input. Thermocouple input modules feature
special circuitry to linearize the output to the actual
temperature rather than the non-linear signal produced
by thermocouple sensors.
