The Watlow EZ-ZONE RM Expansion 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
