Select the correct model according to the range table below.
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 4-20mA, or 0-10V. 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-TC thermocouple signal conditioners accept thermocouple input and provide a linearized and isolated 0-10V or 4-20mA output. Models are available with three different power options, 24Vdc, 115 Vac and 230 Vac.
The DRF-TC 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). To insure maximum measurement accuracy the units feature cold junction compensation, 0.2% linearity and less than 0.1°C/1°C thermal drift due to compensation. Module response time is 250 ms or less.
