The CN2516 Series is part of
a range of new generation of
limit controllers that incorporate
numerous product specification,
communication, display interface
and software improvements that
surpass competitive limit device
offerings in ease of use and
programming. By adding more
versatile features and user-friendly
functionality like digital inputs, an
easy-to-use HMI, jumperless and
auto-hardware configuration,
24 Vdc transmitter power
supply and MODBUS®
communicationacross the
range, the CN2516 limit
controllertransform the
complicated into the simple
while saving you time (as much
as 50% on product set-up),
reducing inventory stock and
virtually eliminating the likelihood
of operator errors. The CN2516
limit controllers are affordable,
well-featured, easy to use and
adaptable with performance
features that work for you to make
limit control simple. The CN2516
is a fail-safe protection device to
prevent damage toequipment or
products. It will shut down process
when a preset temperature is
reached and cannot be reset by
the operator until the process has
returned to a safe condition.
