1Chapter 1: Overview

The EZ-ZONE®PM takes the pain out of solving your thermal loop requirements.

Watlow’s EZ-ZONE®PM controllers offer options to reduce system complexity and the cost of control- loop ownership. You can order the EZ-ZONE®PM as a PID controller or an over-under limit controller, or you can combine both functions in the PM Integrated Limit Controller. You now have the option to integrate a high-amperage power controller output, an over-under limit controller and a high-performance PID controller all in space-saving, panel-mount packages. You can also select from a number of serial communications options to help you manage system performance.

It just got a whole lot easier to solve the thermal requirements of your system. Because the EZ- ZONE® PM controllers are highly scalable, you only pay for what you need. So if you are looking for a PID controller, an over-under limit controller or an integrated controller, the EZ-ZONE®PM is the an- swer.
