WATLOW EZ-ZONE^® Controllers

Watlow's EZ-ZONE Integrated Thermal Loop ISE / Watlow's EZ-ZONE^® controllers require less panel space, minimize system complexity and best of all, lower the total cost of ownership. ISE / Watlow EZ-Zone also decreases design and assembly time. 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 Watlow TRU-TUNE^®+ adaptive control and a variety of industrial communication protocols including EIA 485, EIA 232, EtherNet/IP™ and Modbus^® TCP.

EZ-ZONE RM: Integrated controller allows common controller platform across many applications and functions

1 to 64 PID loop controller	Saves money because only needed loops are purchased
Advanced PID control algorithm	Offers TRU-TUNE+ adaptive control to provide tighter control for demanding applications
Current monitoring for entire system	Detects condition of up to 18 individual outputs and loads through the use of three current transformer inputs
Communication capabilities	Provides a range of protocol choices including Modbus^® RTU, Ethernet/IP™, Modbus^® TCP and DeviceNet™
SPLIT-RAIL™ control	Allows mounting of high and low voltage modules in different cabinets with individual components functioning together even if physically split apart
AUTO CLONE™	Saves time by reducing complexity and automatically configuring a new module with the same parameter settings as the replaced module
SENSOR GUARD™	Prevents customer system shutdown and product scrap or loss by allowing a sensor to be chosen to backup another sensor in case of primary sensor failure

EZ-ZONE PM: Discrete PID controller AND over/under temperature limit

Features	Benefits
Integrated PID and limit controller	Reduces wiring time and termination complexity
