The CN3271 series has been discontinued. Please see the CNi-AL Series as a possible alternative or contact our Engineering department.
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.
