EZ-ZONE® RM Rail Mount Controller

The Watlow EZ Zone® RM multi-loop controller simplifies thermal system management. The EZ-ZONE RM integrated controller family is comprised of six module types:

  • An integrated on-off or PID temperature controller
  • A monitoring and over/under temperature limit controller 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
  • A data logging and field communications access module.

A system is configured by connecting any combination of module types to address the users specific application needs. The EZ-ZONE RM is an extremely flexible and scalable unit allowing easy mixing and matching of I/O to configure as many as 152 control loops and up to 256 monitor points.

Watlow Distributors

Hi-Watt Inc. is known as leading Watlow Distributors carrying an extensive inventory of industrial electric heaters, thermal and process components, temperature sensors and temperature/limit controllers.

In addition to the Watlow RM controller we also carry multi loop controllers such as the Watlow F4 controller, Watlow F4T, and Watlow limit controllers such as the Watlow PM6. Contact us today to find out how we can help you with Watlow RM.

Features & Benefits:
Multiple inputs; from 1 to 152 PID loops of control or monitor up to 256 analog inputs Mix and match I/O to fit any application; from 1 input with 2 outputs to 152 analog inputs with 152 outputs, or monitor up to as many as 256 analog inputs all in one system
Reduce 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
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 DP
USB Port Provides data log retrieval
SPLIT-RAIL control Enables 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 load
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
