Find how signal conditioning works on this link.

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, 115 Vac and 230 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 to 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 minimising 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.
