The Model CN3271 Series High/Low Limit Controller is designed to provide reliable protection of processes, process equipment and personnel. This is a UL listed Overtemperature (or Undertemperature) controller, and FM approved as a limit controller. Universal sensor inputs allow the CN3271 Series to be applied to temperature, pressure and other processes. Versatile, easy to install and simple to operate, the CN3271 Series provides all of the limit control functions and features of larger and more costly controllers, in a space efficient 1.16 DIN package. With an IP-65 and NEMA-4X rated faceplate, the controller is an excellent choice for washdown environments such as food processing plants.

The CN3271 Series offers sophisticated LED displays of process information such as shutdown duration in hours and minutes, and maximum or minimum process value measured during a shutdown. Temperature input is field programmable for °C or °F. Process input decimal points and range are programmable from -1999 to 9999.
