Watlow's EZ-Zone™ RM integrated multi-loop controller can be used as a PID temperature/process controller, an over/under limit controller or these functions can be combined into an integrated controller. Other control functions can be integrated such as high amperage power controller output which creates a complete integrated thermal loop controller all in one space-saving, DIN-rail mount integrated package.

The EZ-Zone RM can be configured with a rage of 1 to 16 modules controlling from 1 to 64 loops. Because the EZ-Zone RM controller is single-loop scalable, you only pay for what you need--leading to exact loop count and unmatched industry flexiblity.

Optional integrated controller functions that can be combined together or ordered in different quantities as desired include:

• PID Control Loops
• Over/under temperature limit control loops
• 10 or 15 ampere power output/heater driver options
• On-board data logging
• Current measurement input
• Sequencer start up and control function
• Programmable timer and counter functions
• Programmable math and logic options
• Multiple communication protocol options
• Mobile configuration with removable secure digital (SD) flash card

Features and Benefits

• Integrated & PID Limit Controller
  • Reduced wiring time and termination complexity compared to connecting discrete products
  • Improves system reliability
  • Reduces termination and installation costs
  • Eliminates compatibility issues often encountered with using many different discrete components and brands
  • Reduces troubleshooting time and downtime costs since the system can specifically identify to the operator any problems with a sensor, controller, solid state relay (SSR) power output or heater load
  • Thermal solution is complete--saving engineering time and labor costs while speeding up project times
• 1 to 64 PID Loop Controller
  • Saves money because only needed loops are purchased
  • Allows a common controller platform across many design applications since both loop count and additional outputs can be ordered in increments of one
• Advanced PID Control Algorithm
  • Offers TRU-TUNE+ adaptive control to provide tighter control form demanding applications
  • Enables auto-tune for fast, efficient start up
• Communications Capabilities
  • Provides a wide range of protocol choices including Modbus RTU, Ethernet/IP™, Modbus TCP, DeviceNet and ProfiBus (future option)
• Current Monitoring for Entire System
  • Detects up to 18 individual outputs and loads through the use of three current transformer inputs (outputs are inside EZ-Zone RM Expansion Module)
  • Saves cost on extra current transformers, panel space, wiring and mounting labor
  • Provides affordable, easy-to-use diagnostics
• SPLIT-RAIL™ Control
  • Allows mounting of low voltage and high voltage modules in different cabinets with individual modules functioning together even if physically split apart
  • Minimizes the length and cost of wire runs and improves system reliability by accommodating inputs located closer to sensors and outputs closer to loads
• AUTO CLONE™
  • Saves time by reducing complexity and automatically configures a new module with the same parameter settings as the replaced module
• SENSOR GUARD™
  • Prevents customer system shutdown and product scrap or loss by allowing a sensor to be chosen to backup another sensor in case of primary sensor failure
• Maximum System Configuration
  • One access module plus up to 16 additional control or expansion modules (any combination), up to 64 loops
