EZ-ZONE® Controller Family
Watlow's EZ-ZONE® controllers decrease design and assembly time, require less panel space, minimize system complexity and best of all, lower the total cost of ownership. Because these products are modular and scalable, you only pay for what you need. You can order the EZ-ZONEs in multiple configurations giving you the flexibility to standardize on the product platform to solve your wide range of application needs.
EZ-ZONE features include RoHS compliance by design, TRU-TUNE®+ adaptive control and a variety of industrial communication protocols including EIA 485, EIA 232, EtherNet/IP™ and Modbus® TCP.
