Watlow's integrated multi-function controllers decrease design and assembly time, require less space, minimize system complexity and best of all, lower the total cost of ownership.

Integrated multi-function products are modular and consistent in features, capabilities and specifications across the range of models. Using this product family helps users adapt to changing requirements because options can be added and models can be switched with minimal investment in learning, design, documentation, startup, commissioning and training. EZ-ZONE® controllers allow control loops and limits to be added in single increments as well as a variety of power switching options. They also allow for easy transfer of wiring from one product to another (consistent termination labeling).

The broad feature set includes standard bus communications, TRU-TUNE®+ adaptive control, timer and counter application blocks, on-board data logging, user-customizable menus and SENSOR GUARD backup to protect loads should a sensor fail. Other features include front-removable electronics, AUTO CLONE configuration backup and restore, NEMA 4X/IP66, Class I, div 2 rating, SD card expandable data logging memory, universal serial bus (USB) connectivity and free configuration software.
