RMC Module • 5 • Chapter 1 Overview

Introduction

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 ability

to configure/monitor the control over a network, Mod-

bus RTU communications is an option. Other commu-

nications protocols are also available (e.g., EtherNet/

IP, DeviceNet, Modbus TCP and Profibus DP) when

used in conjunction with an RM Access (RMA) mod-

ule or when using a Remote User Interface/ Gateway

(RUI/GTW).

Standard Features and Benefits

Integrated PID and over/under safety limit con-

troller in one package

• 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

• Increases user and equipment safety for over/under

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

Communication Capabilities

• Supports network connectivity to a PC or PLC

• Watlow Standard Bus or Modbus

RTU

• Provides plug and play capabilities with Remote

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 op-

tions

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 integrat-

ed solution that minimizes inter-module connec-

tions and potential problems at screw termination

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-Defined

Parameter Default Settings

• Allows customers to save and restore their own de-

fined defaults for machine parameter settings

• Reduces service calls and downtime due to inad-

vertent end user parameter adjustments

RMC Modules Allow for Greater Design Flex-

ibility

• Allows PID loops to be added in increments of one.

• 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 mod-

ule, regardless of which module is connected to the

input sensor
