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.
