Category: Watlow

Advanced PID control algorithm

• Offers TRU-TUNE®+ adaptive control to provide tighter

control for demanding applications

• Enables auto-tune for fast, efficient start-up

Communication capabilities

• Provides a range of protocol options including

universal serial bus (USB) device port, Modbus® RTU,

EtherNet/IP™, Modbus® TCP, DeviceNet™ and

PROFIBUS

USB port

• Provides data log retrieval

SPLIT-RAIL control

• Allows modules mounted in separate high-voltage

and low-voltage cabinets to function as an integrated

system

• Minimizes the length and cost of wire runs and

improves system reliability by locating inputs closer to

sensors and outputs closer to loads

AUTO CLONE

• Reduces time and configuration complexity by

automatically building a new module with the same

parameter settings as the replaced module

SENSOR GUARD

• Prevents unplanned process shutdowns and product

loss by switching to a backup sensor if the primary

sensor fails

Benefits of using an integrated controller solution:

• Reduces wiring time and termination complexity

compared with connecting multiple discrete products

• Improves system reliability

• Reduces termination and installation cost

• Eliminates compatibility issues often encountered with

using various discrete components and brands

• Reduces troubleshooting time and downtime costs

because the system can specifically identify any

problems with a sensor, controller, solid state relay

(SSR) power output or heater load

• Complete thermal solution saves engineering

time and labor costs while shortening project

schedules

Features and Benefits

Multiple inputs; from one to 152 PID loops of

control or monitor up to 256 analog inputs

• Mix and match I/O to fit any application; from one

input with two outputs to 152 analog inputs with

152 outputs, or monitor up to as many as 256 analog

inputs all in one system

• Reduces cost because only required loops are

purchased

• Allows a common controller platform across many

design applications as both loops and outputs can

be ordered in single increments

The EZ-ZONE RM controller simplifies thermal system

management. The EZ-ZONE RM controller family is

comprised of six module types: An integrated on-off or

PID control, monitoring and over/under temperature limit

module, a high-density on-off or PID control module,

a high-density limit only module, an input/output (I/O)

expansion module, a high-density monitor/scanner

module and a data logging and field communications

access module. A system is configured by connecting

any combination of module types to address specific

application needs. The EZ-ZONE RM is extremely flexible

and scalable allowing mixing and matching of I/O to

configure one to 152 control loops and up to 256

monitor points.

Now Watlow’s EZ-ZONE RM is available through

Watlow SELECT®, a program that enables you to quickly

identify, configure and receive your thermal products

faster and easier than ever before.

combined or ordered in different quantities:

• PID control loops
