he 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.
