Watlow EZ-ZONE® RMC Module • 6 • Chapter 1 Overview
A Conceptual View of the RMC Module
The flexibility of the RMC software and hardware allows a large range of configurations. Acquiring a better understanding of the controller’s overall functionality and capabilities while at the same time planning out how the controller can be used will deliver
maximum effectiveness in your application.
The RMC can be connected at the system level to
as many as 17 modules, one of which can be an Access module and the others (16 maximum) can be any
combination of available modules. The user will define each address via the button on the face of each
module. Each installed RMC module must have a
unique Standard Bus address ranging from 1-9, A-F,
where the factory defaults for each is Standard Bus
address 1.
• 1 to 12 outputs (various types)
• Modbus RTU communications
As can be seen above the RMC module is fully scalable with regards to power requirements, number of
loops, inputs, and outputs.
It is useful to think of the controller in three
parts: inputs, functions and outputs. Information
flows from an input to a function to an output when
the controller is properly configured. An RMC module can carry out several functions at the same time,
e.g., PID control, monitoring for several different
alarm situations, monitoring and acting upon Digital Inputs and driving output devices such as heaters, audible alarms, lights. Each process needs to
be thought out carefully and the controller’s inputs,
functions and outputs set up properly.
Getting Started Quickly
The RMC (Controller) can be ordered with up to
four PID loops with default loop configurations (all
loops) out of the box as follows:
• Analog Input functions set to thermocouple, type
J
Inputs
Functions
PID
Heat
Power
Silence
Alarms
Process
Alarm
High
Sequencing
Outputs
Outputs
• Control loops 1-4 use Analog Inputs 1-4
• Heat algorithm set for PID, Cool set to off
• Outputs set to off
• Control mode set to Auto
• Set point set to 75 °F
To enable a loop for heat simply follow the steps below:
1. Navigate to the Setup Page
2. Once on the Setup Page navigate to the Output
Menu and then the output of choice
3. Change the default setting of Off to Heat Power
4. Select the desired loop instance
Functions
Functions use input signals to calculate a value. A
function may be as simple as reading a digital input
to set a state to true or false, or reading a temperature to set an alarm state to on or off. Alternatively,
if a failure with the primary sensing device should
occur, sensor backup could be utilized to avoid an unwanted shutdown.
To set up a function, one of the first things that
must be considered is the function source and in-

stance. For example, if the control is equipped with
Digital Inputs (source) and it was decided to use DI 9
(instance) it can then be associated with an Action to
reset an individual alarm or all alarms. To configure
as such, follow the steps below:
Setup Page (Digital I/O Menu)
Note:
Zones can communicate with one another over the
backplane (local and split rail). Once the system is
configured and running, changing zone addresses
without careful deliberation may cause disruption in
operation.
Some of the user selectable ordering options are
listed below:

• 90-264 Vac to 24Vdc @ 31 watts
• 90-264 Vac to 24Vdc @ 60 watts
• 90-264 Vac to 24Vdc @ 91 watts
2. RMC Module can provide:
• 1 to 4 control loops, limits or CT inputs
• 1 to 9 inputs (various types)
1. Navigate to the Setup Page and then to the Digital
I/O menu.
2. Select the desired instance and set the direction to
input voltage or input dry contact.

3. Navigate to the Setup Page and then the Action
menu.
4. Set the Action Function to Alarm
5. Select which alarm instance will be reset (0 equals
all)
6. Select the Source Function to Digital I/O
7. Select the Source Instance (step 2 above)
8. Select the Source Zone (0 equals the module being
configured).
9. Select the Active Level to execute the desired function.
Watlow EZ-ZONE® RMC Module • 7 • Chapter 1 Overview
This configuration is now complete. When the selected digital input is active the alarm or all alarms that
are latched without a currently existing alarm condition will be reset. If a specific alarm instance (1 - 8)
is selected (step 5) it will be that instance alone that
will be reset.
Note:
Alarms will reset automatically when the condition
that caused the alarm goes back to a non-alarm state
if the alarm latching prompt is set to non-latching

Function
Keep in mind that a function is a user-programmed
internal process that does not execute any action outside of the controller. To have any effect outside of the
controller, an output must be configured to respond
to a function.
Inputs
The inputs provide the information that any given
programmed function can act upon. In a simple form,
this information may come from an operator pushing a button, or as part of a more complex function it
may represent a remote set point being received from
another zone.
Each analog input can be configured for thermistors, thermocouples, or RTDs to read the process
variable. It can also read mV/volts, current or resistance, enabling usage of various devices to read humidity, air pressure, operator inputs and other values. The settings in the Analog Input Menu (Setup
Page) for each analog input must be configured to
match the device connected to that input.
Each digital input reads whether a device is active or inactive. A RM system can be equipped with
multiple digital I/O. Each I/O point must be configured to function as either an input or output with the
direction parameter in the digital I/O Menu (Setup
Page).
Another concept that needs to be understood is
the difference between an input tied to a real-world
device such as a thermocouple and one that is tied to
an internal function.
Analog
Input
Function
Control

Output
Function
Outputs
Outputs can perform various functions or actions in
response to information provided by a function such
as: heat power from the output of the control, using a
digital output to serve as a profile event, drive a light
on or off, unlocking a door or turning on a buzzer.
Assign an output to a function in the Output
Menu or Digital I/O Menu. Then select which instance of that function will drive the selected output.
For example, you might assign an output to respond
to an internal output of a compare function or to retransmit the value of analog input 2 (instance 2).
You can assign more than one output to respond
to a single instance of a function. For example, alarm
2 could be used to trigger a light connected to output
1 and a siren connected to digital output 5.
Input Events and Output Events
Input and output events are internal states that are
used exclusively by profiles. The source of an event
input can come from a real-world digital input or an
output from another function. Likewise, event outputs may control a physical output such as an output
function block or be used as an input to another function.
Actions
Based on a given input (Digital I/O, Event output,
Logic function, etc..) the Action function can cause
other functions to occur. To name a few, starting
and stopping a profile, silencing alarms, turn control
loops off and placing alarms in non-alarm state.
In the example above the analog input function on
the left is tied directly to the control function where
its internal output is routed to a real-world output.
With a slight modification of the graphic above the
example below now ties the real-world inputs directly
to the control and alarm functions. For the sake of
this example the following is true:
- Two unique high process alarms are configured for
analog inputs 1 and 2
- The logic block is configured as an OR function
- The output function is tied to the internal output of
the logical OR function
When either process alarm is true (analog input val-

RM Control Module Connected to an OIT Running Modbus RTU
In this configuration the control module connected
to the OIT is equipped with the Modbus RTU protocol (RMCxxxxxxxxx1xx). It is important to note that
Modbus communications takes place between the
OIT and the control it is connected to. The RM backplane is always using the Standard Bus protocol. If
it is desired that the OIT communicate to both control modules, both control modules would need Modbus communications and then pins CC, CA, and CB
would need to be daisy chained together.

RMC Installation and Removal on a DIN Rail
Modular Backplane Connector
The picture on the right shows the Modular Backplane
Connector, both front and rear view. The rear view
is bringing in to focus a metal clip. If the DIN rail is
grounded the Modular Backplane Connector and the
module connected to it will be also (recommended).
Installing the Modular Backplane Connector
Step 1
Hook backplane assembly to upper edge of DIN rail,
(see rear view above, backplane hook detail that
mates with upper rail edge is circled)
Step 2
Next, rotate back plane assembly downward to en
gage the lower edge of the rail. (Note: Din Rail clip ping distance ranges from 1.366 -1.389 inches. The
back plane assembly will not latch onto the rail suc cessfully if the rail is out of dimension).
Step 3
For final positioning and locking, the red tab is to
be pushed upward to further engage the bottom
edge of the rail with an over center snap action
latch. (The red locking tab protrudes from the bot tom side of the back plane assembly).
Installing Multiple Modular Backplane Connectors
Multiple modules are easily aligned and latched together. Each module includes matched mating geometry that facilitates accurate and consistent interconnections. The recommended method of multi-module
attachment is to first attach individual modules to
the rail separately and second to laterally slide the
modules together until they touch. (Refer to steps 1&2
above). When the multi-module system is attached and
laterally positioned to the desired placement the locking tab should be engaged to secure the control system
to the rail, (Refer to step 3 above).
Module Installation
In the picture to the right notice that the arrow is
pointing at the top lip of the module (on side). When installing the module simply slide this lip over the top of
the Modular Backplane Connector and then push down
on the rear of the module where it will seat on the two
posts just above the green connector.
Watlow EZ-ZONE® RMC Module • 16 • Chapter 2 Install and Wire
Module Removal
To remove a module from the
Modular Backplane Connector
find the red tab protruding from
the bottom of the module and
pull back on it as shown to the
right. While pulling back on the
red tab the two mounting posts
will release the module where the
module can then be lifted up and
out of the Modular Backplane
Connector.
Removal of the Modular Backplane Connector
A module can be removed from
the Modular Backplane Connector
by inserting a screw driver into
the red locking tab just behind
the green connector and applying
downward pressure on the tab by
lifting the screwdriver upwards.
When released, the tab will move
downward and the connector can
then be lifted up off of the DIN
rail.

Internal Circuitry
Note:
As a switched DC output; this output is a constant current output delivering
750 mW, current limited to 400 mA. The internal supply does have a maximum
open circuit voltage of 22 VDC and minimum open circuit voltage of 19 VDC.
Pin Z7 is shared to all digital outputs. This type of output is meant to drive solid
state relays, not mechanical relays.
As an open collector output, use an external power supply with the negative
wired to B7, the positive to the coil of a pilot mechanical relay and the other
side of the coil wired to D_. Each open collector output can sink 1.5 A with
the total for all open collector outputs not exceeding 8 amperes. Ensure that a
kickback diode is reversed wired across the relay coil to prevent damage to the
internal transistor.
