Watlow EZ-ZONE RM Scanner Module (RMS) Multi-Function Controller

The Watlow EZ-ZONE® RM Scanner Module controller 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.

Benefits of using an integrated controller solution:

• Reduces wiring time and termination complexity compared with 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

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
