Integrated Multi-Function Controllers


The EZ-ZONE® RM controller simplifies thermal system management. The EZ-ZONE RM integrated controller family is comprised of six module types: an integrated on-off or PID control, 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 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.

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
