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 include 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, and complete thermal solution saves engineering time and labor costs while shortening project schedules.
