Description
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-PR signal conditioneraccepts a dc process signal inputand provides an isolated 0 to 10Vdc or 4 to 20 mA output. Modelsare available with three differentpower options, 24 Vdc, 120 Vacand 240 Vac.
The DRF-PR are ideally suited for industrialapplications. They feature galvanic isolation between input,output and power up to 3500 Veff (model specific).Module response time is 70 ms or less.
