DIN Rail DC or AC Current Input Signal Conditioners
DC and AC Current Input Signal Conditioners
- AC/DC Current Input Ranges from 0 to 100 mA to 0 to 5 A
- Accuracy 0.3%
- Response Time for DC Signals, 70 ms
- Response Time for AC Signals, 250 ms
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-IDC and the DRF-IAC current signal conditioners accept dc and ac currents respectively and provide 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-IDC and DRF-IAC are ideally suited for industrial applications. All models mount on a standard 35 mm DIN rail and provide galvanic isolation between input, output and power up to 3500 Veff (model specific).
