Introduction
The EZ-ZONE
®
Rail Mount Expansion module
(RME) takes the pain out of adding I/O points to
your RM system architecture.
It just got a whole lot easier to solve the thermal
requirements of your system. The RME 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 ability
to configure/monitor the control over a network, oth-
er 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).
Standard Features and Benefits
• Provides two mounting options (DIN rail, chassis
mount)
• Reduces wiring time and termination complexity
compared to connecting discrete products
• Reduces panel space and installation cost
Integrated power controller output
• Provides an optional dual Solid-State Relay (SSR)
outputs, which can drive up to 10 amps into resis-
tive loads. Terminals for the ring lug connection is
optional
• Reduces component count and cost of ownership
• Saves panel space and simplifies wiring
Communication Capabilities
• Supports network connectivity to a PC or *PLC
• Provides a wide range of *protocol choices includ-
ing Modbus
®
RTU, EtherNet/IP™, Modbus
®
TCP,
DeviceNet™ and Profibus DP
* When used with the optional RMA or Remote User
Interface/Gateway
Additional control integration options
• Provides a sequencer function
• Includes programmable timer functions
• Includes programmable counter functions
• Allows for simple math and logic programming op-
tions
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
• 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
RME Handles High Ambient Temperatures
• Operates in an unprecedented temperature range
of -18 to 65°C (0 to 149°F) for cabinets and panel
enclosures with elevated temperature levels
Optional Access Module Available
• Serves as a configuration station
• Provides communication capabilities between the
other modules and the PC or PLC
• Stores corresponding module parameter settings
for easy auto-configuration of other additional
modules or replacement modules
• Serves as a configuration station, which programs
initial module setup or automatic programming of
modules if swapping out after initial installation
• Provides a USB port for uploading and download-
ing configuration or data log files directly to a PC
• Saves time and increases reliability of parameter
setting
• Logs process data
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
RM Modules Allow for Greater Design Flex-
ibility
• Saves money because you do not pay for any more
than you need and don’t settle for any less func-
tionality than you need
Synergistic Module Control (SMC)
• Allows outputs selected for control (heat/cool),
alarms or events to be located in any physical
module, regardless of which module is connected
to the input sensor
Split-Rail Control (SRC)
• Allows modules to be mounted together or mount-
ed remotely from one another
• Shares control operation via Synergistic Module
Control (SMC) capability
• Allows individual modules to be mounted closer
to the physical input and output devices to which
they are wired
• Improves system reliability and lowers wiring
costs
