Introduction
The Protege DIN Rail 8 Output Expander extends the number of outputs on the system by 8, featuring high
current Form C relays for controlled automation of building systems including lighting and HVAC.
Flexible module network architecture allows large numbers of modules to be connected to the RS-485 module
network. Up to 250 modules can be connected to the Protege system in any combination to the network, over a
distance of up to 900M (3000ft). Further span can be achieved with the use of a network repeater module.
The current features of the output expander include:
⦁Secure encrypted RS-485 module communications
⦁8 outputs
⦁Industry standard DIN rail mounting
⦁Online and remote upgradable firmware

Grounding Requirements
An effectively grounded product is one that is intentionally connected to earth ground through a ground
connection or connections of sufficiently low impedance and having sufficient current-carrying capacity to
prevent elevated voltages which may result in undue hazard to connected equipment or to persons.
Grounding of the Protege system is done for three basic reasons:
1. Safety
2. Component protection
3. Noise reduction
Safety Grounding
The object of safety grounding is to ensure that all metalwork is at the same ground (or earth) potential.
Impedance between the Protege system and the building scheme ground must conform to the requirements of
national and local industrial safety regulations or electrical codes. These will vary based on country, type of
distribution system and other factors. The integrity of all ground connections should be checked periodically.
General safety dictates that all metal parts are connected to earth with separate copper wire or wires of the
appropriate gauge.
Earth Ground Connection
The DIN rail enclosure and the DIN rail modules must be grounded to a suitable single-point earth ground
connection in the installation. A minimum 14AWG solid copper wire (or thicker, in accordance with local
authorities) shall be used from the Protege system's earth connection points.
The DIN rail enclosure includes an earth ground single-point link connection via the metallic enclosure. This single-
point link is the Protege system's earth ground. All modules that have earth ground connections and that are
installed in the same enclosure shall be connected to this single point. A single-point earth ground connection
avoids the creation of ground loops in the system and provides a single reference point to earth ground.

Mounting
Protege DIN rail modules are designed to mount on standard DIN rail either in dedicated DIN cabinets or on
generic DIN rail mounting strip.
When installing a DIN rail module, ensure that there is adequate clearance around all sides of the device and that
air flow to the vents of the unit is not restricted. It is recommended that you install the module in a location that
will facilitate easy access for wiring. It is also recommended that the module is installed in an electrical room,
communication equipment room, secure cabinet, or in an accessible area of the ceiling.
1. Position the DIN rail module with the labeling in the correct orientation.
2. Hook the mounting tabs (opposite the tab clip) under the edge of the DIN rail.
3. Push the DIN rail module against the mount until the tab clips over the rail.
Removal
A Protege DIN rail module can be removed from the DIN rail mount using the following steps:
1. Insert a flat blade screwdriver into the hole in the module tab clip.
2. Lever the tab outwards and rotate the unit off the DIN rail mount.

LED Indicators
Protege DIN rail modules feature comprehensive diagnostic indicators that can aid the installer in diagnosing faults
and conditions. In some cases an indicator may have multiple meanings depending on the status indicator display
at the time.
Status Indicator
The status indicator displays the module status.
State Description
Fast flash (green) Module attempting registration with controller
Slow flash (green) Module successfully registered with controller
Flashing (red) Module communications activity
When the fault and status indicators are flashing alternately, the module is in identification mode, enabling the
installer to easily identify the module in question. Upon either a module update or the identification time period
expiring, the module will return to normal operation.
Fault Indicator
The fault indicator is lit any time the module is operating in non-standard mode. If the fault indicator is flashing, the
module requires a firmware update or is in firmware update mode. When the fault indicator is on, the status
indicator will flash an error code.
State Description
Continuous slow flash (red) Module is in boot mode awaiting firmware update
Constantly on (red) Module is in error state and will flash an error code with the status indicator
Power Indicator
The power indicator is lit whenever the correct module input voltage is applied across the N+ and N- terminals.
State Description
Constantly on (green) Correct module input voltage applied
Constantly off Incorrect module input voltage applied
Output Indicators
The output indicators will show the status of the outputs.
State Description
Constantly on (red) Output is ON
Constantly off Output is OFF
PRT-PX8-DIN | Protege DIN Rail 8 Output Expander | Installation Manual 15

Error Code Indication
When the module attempts to register or communicate with the system controller a registration error can be
generated indicating that it was not successful.
Error Code Display
The following table is only valid if the fault indicator is constantly on and the status indicator is flashing red.
If the fault indicator is flashing the module requires a firmware update or is currently in firmware update mode.
The status indicator will flash red with the error code number. The error code number is shown with a 250ms on
and off period (duty cycle) with a delay of 1.5 seconds between each display cycle.
Flash Error Description
1Unknown Error Code
The error code returned by the system controller could not be understood by the module.
2
Firmware Version
The firmware version on the module is not compatible with the system controller. To clear this error,
update the module using the module update feature in the controller's web interface.
3
Address Too High
The module address is above the maximum number available on the system controller. To clear this
error change the address to one within the range set on the system controller, restart the module by
disconnecting the power.
4
Address In Use
The address is already in use by another module. To clear this error set the address to one that is not
currently occupied. Use the view network status command to list the attached devices, or the network
update command to refresh the registered device list.
5
Controller Secured Registration Not Allowed
The controller is not accepting any module registrations. To allow module registrations use the network
secure command to change the setting to not secured.
6Serial Number Fault
The serial number in the device is not valid. Return the unit to the distributor for replacement.
7
Locked Device
The module or system controller is a locked device and cannot communicate on the network. Return
the unit to the distributor for replacement.

*The total combined current refers to the current that will be drawn from the external power supply to supply the
expander and any devices connected to its outputs. The auxiliary outputs are directly connected via thermal
resettable fuses to the N+ N- input terminals, and the maximum current is governed by the trip level of these fuses.
It is important that the unit is installed in a dry cool location that is not affected by humidity. Do not locate the unit
in air conditioning or a boiler room that can exceed the temperature or humidity specifications.
Integrated Control Technology continually strives to increase the performance of its products. As a result these
specifications may change without notice. We recommend consulting our website (www.ict.co) for the latest
