Description

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-LC signal conditioner accepts a load cell 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-LC are ideally suited for industrial applications. The DRF-LC feature galvanic isolation between input, output and power up to 3500 Veff (model specific). Module response time is 75 ms or less.

The FAR-1 power supply is an ideal companion product for the DRF-LC. It provides a regulated 10Vdc output that may be used to power up to 4 load cells.
