The DRSL-TC Series thermocouple
input DIN rail signal conditioners
provide a competitive choice in terms
of both price and technology for
interfacing thermocouple inputs to
SCADA systems or PLC equipment.
The DRSL-TC and DRSL-TC-ISO
can be used for signal conversion of
standard Type J or K thermocouple
inputs into unipolar analog signals.
The DRSL-TC-ISO isolated model
offers 3-way isolation between input,
output and supply and provides surge
suppression and protects control
systems from transients and noise.
Low power consumption facilitates
DIN rail mounting without the need
for any air gap. Easy configuration
of more than 1000 factory calibrated
measurement ranges is done via
DIP-switches. The unit operates over
a wide temperature range from
-25 to 70°C (-13 to 158°F).
