Description The DRF series DIN rail signal conditioners aredesigned to accept a broad range of input signals,such as ac and dc voltage and current, frequency,temperature (thermocouple and RTD), and processtransducers, and provide standard process outputsof either 4 to 20 mA, or 0 to 10 Vdc. The DRF seriesfeature a modern housing design, that is easilymounted on standard 35 mm DIN rails. Connectionsare safely and securely made through pluggablescrew terminal connectors, with input and outputconnections on the opposite sides of the module.
The DRF-IDC and the DRF-IACcurrent signal conditioners acceptdc and ac currents respectivelyand provide an isolated 0 to 10 Vdcor 4 to 20 mA output. Models areavailable with three different poweroptions, 24 Vdc, 120 Vac and240 Vac.The DRF-IDC and DRF-IACare ideally suited for industrialapplications. All models mounton a standard 35 mm DIN railand provide galvanic isolationbetween input, output and powerup to 3500 Veff (model specific).
