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 Integrat-
ed Limit Controller. You now have the option to in-
tegrate 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 se-
rial communications options to help you manage sys-
tem 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 con-
troller, an over-under limit controller or an integrat-
ed controller, the EZ-ZONE PM is the answer.
Standard Features and Benefits
Advanced PID Control Algorithm
• TRU-TUNE+
®
Adaptive tune provides tighter con-
trol for demanding applications.
• Auto Tune for fast, efficient start ups
EZ-ZONE configuration communications and
software
