EZ-ZONE® RM Mulit-Loop Controllers
EZ-ZONE® RM Controller Modules can provide from 1 to 152 Loops of Integrated Temperature, Process, Limit & Power 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 PID 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

- 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
