Watlow EZ-ZONE
®
PMI Controller • 7 • Chapter 1 Overview
Introduction
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 con-
troller, or you can combine both functions in the PM Integrated 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 industrial serial communications options to help you manage
system performance.
