Description

Description

The CN2504 Series is part of a range of newgeneration series of limit controllers that incorporatenumerous product specification, communication,display interface and software improvements thatsurpass competitive limit device offerings in ease ofuse and programming.By adding more versatile features and user-friendlyfunctionality like digital inputs, an easy-to-useHMI, jumperless and auto-hardware configuration,24 Vdc transmitter power supply and MODBUS®communication across the range, the CN2504 limitcontroller transform the complicated into the simplewhile saving you time (as much as 50% on productset-up), reducing inventory stock and virtuallyeliminating the likelihood of operator errors.The CN2504 limit controllers are affordable, wellfeatured,easy to use and adaptable with performancefeatures that work for you to make limit control simple.The CN2504 is a fail-safe protection device to preventdamage toequipment or products. It will shut down aprocess when a preset temperature is reached andcannot be reset by the operator until the process hasreturned to a safe condition.
