The CN8100 Series controller is a
low-cost, general purpose 1⁄4 DIN
temperature controller, ideal for
OEM or replacement applications.
Microprocessor-based and accurate
to ±0.3% FS, it may be ordered as
either a PID controller, on/off
controller or limit safety device.

As a separate safety feature to your
control application, the CN8121-R1
limit controller provides reliable
high/low temperature limit shut-off
control for most machine and
process control applications
including environmental chambers,

furnaces, ovens and packaging
machinery. As a high-limit device,
these controllers have a normally
energized SPST latching output
relay which becomes de-energized
whenever the process variable (PV)
exceeds a selected setpoint value.
Reset of the latching output relay is
done by holding the parameter
button for 3 seconds on the front
panel of the controller, or by cycling
power to the controller.
