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 CodeRange
20HZ0 to 20 Hz
40HZ0 to 40 Hz
60HZ0 to 60 Hz
100HZ0 to 100 Hz
200HZ0 to 200 Hz
300HZ0 to 300 Hz
500HZ0 to 500 Hz
1KHZ0 to 1 KHz
Range CodeRange
2KHZ0 to 2 KHz
3KHZ0 to 3 KHz
5KHZ0 to 5 KHz
10KHZ0 to 10 KHz
20KHZ0 to 20 KHz
30KHZ0 to 30 KHz
50KHZ0 to 50 KHz

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.

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.
