Watlow EZ-ZONE®PM PID Controller •6 •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
controller, 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 con-
troller 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 man-
age system performance.
