The CN7500 Series temperature/process controller’s
advanced control features can handle the most
demanding temperature or process applications.
Enclosed in a compact 1⁄32 DIN housing, the CN7500
has dual, 4-digit LED displays for local indication of
process value and setpoint. Control methods include
on/off, PID, autotune, and manual tune. PID control is
supported with 64 temperature and time (ramp/soak)
control actions. The dual-loop output control allows
simultaneous heating and cooling. The second output
can be configured as an alarm mode using one of the
13 built-in alarm functions.
RS485 communications is standard. Up to
247 communication addresses are available,
with transmission speeds of 2400 to 38,400 bps.
Other features include universal inputs, selectable
temperature units (°C/°F), selectable resolution,
quick sampling rate, and security protection.
