Watlow RM Multi Loop Temperature Controller

Watlow RM controllerThe Watlow EZ Zone® RM multi loop controller simplifies thermal system management. The EZ-ZONE RM integrated controller family is comprised of six module types:

  • An integrated on-off or PID temperature controller
  • A monitoring and over/under temperature limit controller 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
  • A data logging and field communications access module.
  • A system is configured by connecting any combination of module types to address the users specific application needs. The EZ-ZONE RM is an extremely flexible and scalable unit allowing easy mixing and matching of I/O to configure as many as 152 control loops and up to 256 monitor points.

    Features & Benefits:
    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
    • Reduce 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
    Advanced PID control algorithm
    • Offers TRU-TUNE®+ adaptive control to provide tighter control for demanding applications
    • Enables auto-tune for fast, efficient start-up
    Communication capabilities
    • Provides a range of protocol options including universal serial bus (USB) device port, Modbus® RTU, EtherNet/IP™, Modbus® TCP, DeviceNet™ and PROFIBUS DP
    USB Port
    • Provides data log retrieval
    SPLIT-RAIL control
    • Enables modules mounted in separate high-voltage and low-voltage cabinets to function as an integrated system
    • Minimizes the length and cost of wire runs and improves system reliability by locating inputs closer to sensors and outputs closer to load
    • Reduces time and configuration complexity by automatically building a new module with the same parameter settings as the replaced module
    • Prevents unplanned process shutdowns and product loss by switching to a backup sensor if the primary sensor fails
