Watlow EZ-Zone PM Controllers
Watlow EZ-Zone™ RM Rail Mount Controllers -
Integrates Multiple Controller Functions Saving Time, Space & Cost
Introduces High-Density Modules which Control from 1 to 152 Loops

Watlow's EZ-Zone™ RM integrated multi-loop controller family offers products that simplify thermal system management. The RM family is comprised of six module types: an integrated On/Off/PID control, monitoring and over/under temperature limit module (RMC), a high-density On/Off/PID control module (RMH), a high-density limit only module (RML), an input/output "I/O" expansion module (RME), a high-density monitor/scanner module (RMS) and a data logging and field communications access module (RMA). A system is configured by connecting any combination of module types to address specific application needs. The RM is extremely flexible and scalable allowing you to mix and match I/O to configure 1 to 152 control loops and up to 256 monitor points. 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 152 PID Loop Controller or Monitor up to 256 Analog Inputs
    • Mix and match I/O to suit the 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
    • 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 Univeral Series Bus (USB) device port, Modbus RTU, Ethernet/IP™, Modbus TCP, DeviceNet™ and ProfiBus
  • USB Port
    • Provides data log retrieval
  • 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
    • Saves time by reducing complexity and automatically configures a new module with the same parameter settings as the replaced module
    • 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
