Watlow EZ Zone PM Control


Watlow’s EZ-ZONE™ PM controller extends the integrated control loop functions first introduced in the EZ-ZONE ST integrated controller to the popular 1/32 and 1/16 DIN panel mount package sizes.Watlow’s EZ-ZONE PM controller offers solutions to reduce system complexity and lower the cost of control loop ownership. You can configure the EZ-ZONE PM as a discrete PID controller with adaptive tuning, as a discrete, agency approved, over/under limit controller, or as an integrated control loop solution by combining the PID functionality, over/under limit functionality and high amperage NO-ARC power switching output in a single panel mount package.

Watlow’s new EZ-ZONE ST integrated thermal loop solid state controller also offers complete thermal system control in a single package solution. You get a PID temperature controller already connected to a high amperage solid state relay with the option of adding a properly sized heat sink, an over/under temperature limit, a shut-down power contactor, digital communications and a remote user interface in one complete and professionally engineered product.

Significant reductions in thermal loop installation costs are realized when the limit control function and the power switching function are integrated into a single panel mount package. Having a less crowded panel, fewer wiring connections, fewer discrete components and better thermal loop monitoring with error reporting are all benefits to the user. 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™ or Modbus® TCP.
