The CN7200 series 1⁄4 DIN
temperature/process controllers are
designed to accept thermocouple,
RTD, current or voltage input and
provide dual outputs for control.
Available outputs include relay/
relay, DC pulse/relay, current/relay,
or linear voltage/relay. The units
can be programmed for ON/OFF,
PID, auto-tuning, or manual tuning
control methods.
The PID control is supported by
64 ramp/soak actions. The CN7200
series also includes two additional
alarm outputs. The second relay
output can be reconfigured as a
third alarm output. The alarm type
can be selected from 13 different
preprogrammed alarm functions.
The controller features dual LED
displays for local indication of
process and setpoint values.
