warranty period specified. This warranty does not
apply to damage resulting from transportation,
alteration, misuse or abuse. The purchaser must
use Watlow parts to maintain all listed ratings.

Overview
The EZ-ZONE PM Express controllers take the pain
out of solving your thermal loop requirements
while reducing the cost of control-loop ownership.
You can order this control as a single loop PID
controller with a high-amperage power output in
either a 16 th or 32 nd DIN panel-mount package.
It just got a whole lot easier to solve the ther-
mal requirements of your system. Because the
EZ-ZONE family of controls are highly scalable

Made in the U.S.A.
where you pay only for what you need. So if you
are looking for a single or multi-loop PID control-
ler, an over-under limit controller or an integrated
controller (PID and Limit), the EZ-ZONE family of
controls can meet all of your needs. Point your
browser to http://www.watlow.com to find out
more about the EZ-ZONE family of controls.
For this particular control, serial communications
is accomplished using Watlow's Standard Bus

trols and communicate using other popular proto-
®
cols such as Modbus RTU/TCP , EtherNet/IP
DeviceNet TM or Profibus DP consider using the
EZ-ZONE family Remote User Interface/Gateway
(RUI/GTW).
