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-RTD RTD signal conditioners accept 2 or 3 wire 100 platinum RTDs as input 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-RTD 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). Module response time is 250 mS or less.

The manual outlines how to manually adjust the input/output. Can you confirm the DRF-RTD unit ships calibrated or pre-adjusted already? Thank you.
The unit comes reset to the range that the part number calls out. It does not however include any type of calibration certificate your order will include a certificate of conformance at no charge
