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-FR signal conditioner
accepts a frequency 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-FR are ideally suited for
industrial applications. All models
mount on a standard 35mm DIN
rail and provide galvanic isolation
between input, output and power
up to 3500 Veff .
Module response time is 250 ms
or less.
Adjustable Input Ranges
The front door of the housing provides easy access
span and offset potentiometers which may be used
field adjust the input and output signal range. The ranges shown in the Range Table
below are supported.
| Range Code | Range |
| 20HZ | 0 to 20 Hz |
| 40HZ | 0 to 40 Hz |
| 60HZ | 0 to 60 Hz |
| 100HZ | 0 to 100 Hz |
| 200HZ | 0 to 200 Hz |
| 300HZ | 0 to 300 Hz |
| 500HZ | 0 to 500 Hz |
| 1KHZ | 0 to 1 KHz |
|
|
| Range Code | Range |
| 2KHZ | 0 to 2 KHz |
| 3KHZ | 0 to 3 KHz |
| 5KHZ | 0 to 5 KHz |
| 10KHZ | 0 to 10 KHz |
| 20KHZ | 0 to 20 KHz |
| 30KHZ | 0 to 30 KHz |
| 50KHZ | 0 to 50 KHz |

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.
