WATLOW RM Multi-Zone CONTROLLERS

Integrated Multi-Function Controllers

EZ-ZONE^® RM

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

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
