The CN8100 Series may be ordered as either a PID or On/Off controller or as a Limit Safety Device.The 1/4; DIN models are low cost and ideal for OEM or replacement applications. They are microprocessor-based and accurate to ± 0.3% FS.


As a separate safety feature to your control application, the CN8121-R1 high limit safety device 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 SPDT 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 from a reset pushbutton on the front panel of the controller.
