RM Multi Loop control

The EZ-ZONE®RM controller family simplifies thermal system management. The EZ-ZONE RM controller family is comprised of six module types: an integrated on-off or PI control, monitoring and over/under temperature limit 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.

Optional integrated controller functions can be combined or ordered in different quantities:

• PID control loops

• Over/under temperature limit control loops

• 10 and 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 protocols options

• Mobile configuration with removable secure digital (SD) flash card

Benefits of using an integrated controller solution:

• Reduces wiring time and termination complexity compared to connecting multiple discrete products

• Improves system reliability

• Reduces termination and installation cost

• Eliminates compatibility issues often encountered with using various discrete components and brands

• Reduces troubleshooting time and downtime costs because the system can specifically identify any problems with a sensor, controller, solid state relay (SSR) power output or heater load

• Complete thermal solution saves engineering time and labor costs while shortening project schedules

Features and 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

• Reduces 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

• USB port

• Provides data log retrieval

Split-Rail control

• Allows 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 loads.

Auto-Clone

• Reduces time and configuration complexity by automatically building a new module with the same parameter settings as the replaced module.

Sensor-Guard

• Prevents unplanned process shutdowns and product loss by switching to a backup sensor if the primary sensor fails.
