Monitor and control temperature or process applications
with precision using the CN7800 Series controllers. The
CN7800 Series provides dual LED displays for local
indication of process value and setpoint value. Control
methods include on/off, PID, auto-tune and manual-tune.
PID control is supported with 64 ramp/soak control
actions. Two additional alarm outputs are standard on
the CN7800 Series. The alarm outputs can be quickly
configured by using the 13 built-in alarm functions. The
controller communicates easily with the built-in
RS485 interface.
