商品説明
This product series is no longer available. For potential replacements please see
CN-4000-Series
Please consult an application engineer for a more specific recommendation.
The CN2504 Series is part of a range of new
generation series 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®
communication across the range, the CN2504 limit
controller transform 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 CN2504 limit controllers are affordable, wellfeatured,
easy to use and adaptable with performance
features that work for you to make limit control simple.
The CN2504 is a fail-safe protection device to prevent
damage toequipment or products. It will shut down a
process when a preset temperature is reached and
cannot be reset by the operator until the process has
returned to a safe condition.
