EZ-ZONE® PM Panel Mount Controller

EZ-ZONE® PM Controllers
Take the Pain Out of
Meeting Your Thermal
Loop Requirements

SPECIFICATION SHEET

The EZ-ZONE® PM panel mount controller from Watlow®
offers control options to reduce system complexity and the
cost of thermal loop ownership. It can be ordered as a PID
controller, an over/under limit controller or its functions can
be combined into an integrated controller. An 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 is also
available. Many communication options are offered to
support connectivity needs.

Because the EZ-ZONE PM controller is highly scalable, you
pay only for what is needed. This controller is available in

1

/16, 1/8 and 1/4 DIN panel mount packages. The EZ-ZONE PM
controller is easy to use and is ideal for PID, over/under limit
or integrated controller needs.
