Watlow’s Fiber Optic Temperature Measurement and Control

System Offers Improved Accuracy, Precision and Reliability in

High RF Environments

By combining advances in fluorescent temperature

sensing with the power of the proven EZ-ZONE® RM

control system, Watlow® developed a best-in-class fiber optic

temperature measurement and control system that provides

industry-leading performance for your specific application.

By integrating fiber optic sensing capabilities into the

EZ-ZONE RM control system, users will save space, improve

performance with faster response times while simplifying

their control system.

Watlow’s EZ-ZONE RMZ and EZ-ZONE RMF make the system

adaptable to specific customer requirements. Both are

compatible with all other modules within the EZ-ZONE RM

family and self-discover all existing modules within the

system making a seamless integration into your temperature

control/logic system.

Key component of a Watlow Ecosystem Solution

• Integrates EZ-ZONE® RM, RMA PLUS™ and PM PLUS® controllers and

ASPYRE AT power controllers for a complete solution including Modbus®

TCP, EtherNet/IP™, or EtherCAT® communication.

• Eliminates discrete wiring between temperature controllers and power

controllers for each heater through the highspeed bakcplane interface with

Watlow controllers.

• Enables data collection and diagnostics from temperature, process and

power control

• Customizes for your application with programmable function blocks including

logic, math, compare and more.

This EZ-ZONE RM controller family is extremely flexible and scalable

allowing mixing and matching of I/O for one to 152 control loops and

limits, up to 256 monitor points and other controller functions including

counters, timers, math, and logic in an integrated control solution.

The DIN-rail mountable modules can be used as stand-alone controllers,

but when combined with other EZ-ZONE RM modules, PM PLUS controllers

and ASPYRE AT power controllers they form a Watlow Ecosystem Solution

sharing I/O and function block programming as a system.

The EZ-ZONE RM controller family includes several module types:

A temperature and process control, monitoring and over/under temperature

limit module, a high-density control module, a high-density limit module,

an input/output (I/O) expansion module, a high-density monitor/scanner

module, a fiber optic temperature sensor module, an EtherCAT® module

and a data logging and field communications access module. A system is

configured by connecting any combination of module types and configuring

with Watlow’s COMPOSER® software to address specific application needs.

Improve Processes

Designed to give a fast stable response even in heavy industrial environments,

EFit SCR power controller will enable you to run continuously optimized heating

processes with minimum down time. This faster throughput improves OEE

(Overall Equipment Effectiveness), helping you achieve your KPIs

(Key Performance Indicators).

Increase throughput

• Maximise utilisation of plant equipment thanks to fast stable control response

Reduce down time

• Reliably operates in heavy industrial conditions — high immunity to electromagnetic disturbances

• Robust — operates in high temperature, humidity and altitude environments

Control Precisely

EFit SCR controller offers built in power stabilization and a variety of firing modes 

for different types of load, which lead to energy savings and higher quality end

products when compared to more basic power controllers.

Reduce hidden energy costs

• No wasted energy — built in compensation provides stable power control even

during power fluctuations, eliminating unexpected changes in heater temperature

• Better power factor— save hidden energy costs with dedicated firing modes for

each type of load, including a variety of burst modes that provide an efficient

alternative to Phase Angle, such as advanced single cycle firing to reduce flicker

in short-wave infrared heaters

Consistently high quality end products that comply to standards

• No scrap or rework – linearity better than ±2% of range, accurately controls

heaters and maintains the correct load temperature

The perfect fit for simple heating applications

Some Industrial processes such as heat treatment require precise temperatures

in order to comply with regulations and it is imperative that the workpiece

temperature is kept within specific limits. This can be difficult to achieve in

industrial plants where the operation of large machinery can cause fluctuations

in the voltage supply. In the case of resistive heaters a variation of 10% in the

supply voltage will generate a 20% variation in the power to the load, resulting

in undesirable temperature fluctuations. EFit SCR controller contains built in

compensation that continues to apply stable power with better than ±2% linearity

at the boundaries of the load, even during fluctuations in the supply. The result is

a reliable, repeatable heating process and high quality end products compliant to

demanding heat treatment standards.

Connect Easily

Straightforward connection and commissioning, combined with a compact format

to maximise use of cabinet space makes EFit controller the perfect fit for power

control in both new and retrofit applications.

Easy Installation

• Nothing to configure — plug and play

• Nothing to fix — just clip onto DIN rail

• Minimal connection — pre-wireable plug in connectors

Easy Integration

• Compact dimensions reduce cabinet costs

• Integrates worldwide — global standard approvals and international voltages

• Consistent form factor — same height and depth across the range

• Ideal form and fit drop in replacement for EurothermTE10A

Easy to integrate and commission, yet highly cost effective, the EFit power

controller provides no compromise control for resistive and infrared heating

elements.
