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-TC thermocouple signal
conditioners accept thermocouple input
and provide a linearized and isolated 0
10 Vdc or 4 to 20 mA output. Models are
available with three different power
options, 24Vdc, 120 Vac and 240 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.
