EZ-Zone PM Controllers are DISCONTINUED
Contact us to upgrade to a new EZ-Zone PM Plus or PM Legacy Controller.

Watlow's EZ-Zone™ PM panel mount controller offers control options to reduce system complexity and the cost of thermal loop ownership. You can order the EZ-Zone PM as a PID controller, an over/under limit controller, or these functions can be combined into an integrated controller. You now have the option to integrate a high amperage power controller output with a high-performance PID controller and an over/under limit controller in one space-saving, panel mount package. A number of serial communication options are available to support your connectivity needs.

Because the EZ-Zone PM controller is high scalable you only pay for what you need. This controller is available in all panel mount packages. If you are looking for a PID controller, an over/under limit controller or an integrated controller, the EZ-Zone PM will make your life easier.

The new Watlow EZ-Zone™ PM Express is the next generation of controllers, leveraging the strong legacy of Watlow's Series 93, Series 935 and Series SD Controllers where easy-to-use features are needed for basic applications. It includes one universal input and the option for up to two outputs and is available in all DIN panel mount packages. The EZ-Zone PM Express can be ordered as a PID process controller or a dedicated over and under-temperature limit controller. The simplified "Express" menu fits basic applications with a user-friendly interface supported by two menus and a streamlined list of parameters. It eliminates user complexity often encountered when having to deal with more advanced controllers and unnecessary features. Like all Watlow EZ-Zone controllers, it comes with Standard Bus Communications for easy product configuration via PC communications protocol and free software. If you are looking for a simple and easy-to-use, but very powerful, basic PID controller or limit controller, then the EZ-Zone PM Express will be the ideal controller to use.
