The Watlow EZ-ZONE RM Expansion 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 1 to 152 control loops and up to 256 monitor points.

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

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
  • 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

Additional Key Functions

  • Configuration communication port (standard bus)
  • Removable modules and connectors
  • Ring lug and front-screw terminal options
  • Profile ramp soak with 400 total steps
  • Retransmit and remote set point input virtually inside controller eliminating costs for input/output hardware
  • User configuration settings can be stored and recalled
  • Thermistor input
  • Elevated operating range of 0 to 149°F (-18 to 65°C)
  • UL® listed, CSA, CE, RoHS, W.E.E.E. FM, SEMI F47-0200, Class 1, Div. 2 rating on selected models

Application Notes

Here's how some of our customers used this product.

Multi-Loop Temperature Controller with Digital Communications

The Background: Our customer builds packaging machines and is looking for temperature controllers to interface with their PLCs.

The Problem: The application has 4 Control Loops and EtherNet/IP is needed to communicate with the PLCs. The customer does not need any local display from the controller.

The Solution: We recommended the Watlow EZ-ZONE RM Control Module which offers the 4 control loops with the Inputs and Outputs needed. The Watlow RM Access Module will attach to the Control Module to provide the EtherNet/IP Communications needed to interface with the PLCs. There is no on-board interface on this unit so they can just install it behind the control panel and their PLC can be the central access point.
