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.

NOTICE: EZ-ZONE RMA (Access) Module NOT FOR NEW DESIGNS. See RMA PLUS. Watlow SELECT™ Product configuration available with instant access to drawings, current lead times, and more.

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.

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.
