9001-registered processes and is backed by a

warranty period specified. This warranty does not
apply to damage resulting from transportation,

Overview
The EZ-ZONE PM 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 control-
ler 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
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 pro-
tocol. If the need arises to network your controls
and communicate using other popular protocols
such as Modbus RTU/TCP
®
, EtherNet/IP
TM
or
DeviceNet
TM
, consider using the EZ-ZONE family
Remote User Interface/Gateway (RUI/GTW).
