The EZ-ZONE
®
Rail Mount Control module (RMC)
takes the pain out of solving your thermal loop re-
quirements whether it be for a single loop, multi-
loop, stand-alone or distributed control applications.
It just got a whole lot easier to solve the thermal
requirements of your system. The RMC module is
provided in a space-saving, rail-mount package and
is highly scalable where you only pay for what you
need. For those applications that require the abil-
ity to configure/monitor the control over a network,
Modbus RTU communications is an option. Other
communications protocols are also available (e.g.,
EtherNet/IP, DeviceNet, Modbus TCP and Profibus
DP) when used in conjunction with an RM Access
(RMA) module or when using a Remote User Inter-
face/ Gateway (RUI/GTW). Using your browser with

Reduces panel space and installation cost
•
Increases user and equipment safety for over/un-
der temperature conditions
Integrated power controller output
•
Includes the patented NO-ARC, which drives up
to 15 amp resistive loads directly
• Reduces component count and cost of ownership
• Saves panel space and simplifies wiring
Current monitoring (traditional or algorithm)
•
Detects heater current flow and provides alarm
indication of a failed output device or heater load
• For use in single phase loads

User Interface (RUI’s) and RMA module
• Free standard bus communications port and free
PC software (EZ-ZONE Configurator)
Additional Control Integration Options
•
Provides a sequencer function
• Includes programmable timer functions
• Includes programmable counter functions
• Allows for simple math and logic programming
options
Advanced PID Control Algorithm
• Offers TRU-TUNE
®
+ adaptive control to provide
tighter control for demanding applications
• Provides auto-tune for fast, efficient startup
Integrated Thermal Loop Diagnostics
• Users can easily tell that the entire thermal sys-
tem is functioning properly
• Provides complete system diagnostics that are far
superior to simple discrete level diagnostics
• Allows for flexible synergistic use of hardware,
such as using one loop's sensor as a backup to an-
other loop in the event of sensor failure.
• Helps prevent load loss or allow for maintenance
to be scheduled when more convenient.
• Provides notification of system problems to help
reduce maintenance and service costs
Off-the-Shelf Designed System Solution
• Improves system reliability with a factory inte-
grated solution that minimizes inter-module con-
nections and potential problems at screw termina-
tion points.
• Reduces installation cost
• Eliminates compatibility headaches often encoun-
tered with using many different components and
brands
Controller Handles High Ambient Tempera-
tures
• Operates in an unprecedented temperature range
of -18 to 65°C (0 to 149°F) for cabinets and panel
enclosures with elevated temperature levels
Memory for Saving and Restoring User-De-
fined Parameter Default Settings
• Allows customers to save and restore their own
defined defaults for machine parameter settings
• Reduces service calls and downtime due to inad-
vertent end user parameter adjustments
