Din-Rail Signal Conditioners

The DRF series of 35-mm DIN-rail signal conditioners accept a broad range of input signals, such as ac and dc V and I, frequency, thermocouple and RTD temperature, and process transducers.

In return they provide standard process outputs of either 4-to-20 mA or 0-to-10 Vdc determined by an internal jumper. Connections are made via plug-in screw terminal connectors. Input and output connections are on opposite sides of the module. Span and offset potentiometers are accessible through a front door on the housing. Input, output, and power circuits incorporate 3.5-kV galvanic isolation.
