DRC-8920,
shown smaller
than actual size

The DRC-8900 Series DIN rail
mount signal conditioners are
ideal for a wide range of process
monitoring applications. Models
are available for a many different
input types including thermocouples,
RTDs, and process voltage or
current. All models isolate and
linearize. The thermocouple input
models also have cold junction
compensation. These signal
conditioners have three way
isolation—input to output, input to
power and output to power. All
models are powered by 24 Vdc
and are housed in a plastic case
with a built-in DIN rail mounting foot.
Connections are made to easily
accessible screw terminals.
