PRT-IO84-DIN | Protege DIN Rail 8 Input 4 Output Expander | Installation Manual 3
Introduction
The Protege DIN Rail 8 Input 4 Output Expander extends the number of inputs by 8, allowing monitoring of a wide
range of EOL capable or open contact sensors for security and building automation purposes; and extends the
number of outputs by 4, 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 input/output expander include:
⦁Secure encrypted RS-485 module communications
⦁8 inputs
⦁4 Form C Relay outputs
⦁Industry standard DIN rail mounting
⦁Online and remote upgradeable 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.

DC Power & Encrypted Module Network
The expander incorporates encrypted RS-485 communications technology, and both module and network power
are supplied by the N+ and N- terminals.
NA NB
Network communications input
from the Controller or previous
module
N+ N-
Connection of the communications and DC supply should be performed according to the diagram shown above. It
is important that the N+ network communications power be 12VDC supplied from an independent battery backed
power supply unit capable of supplying the required voltage to all devices on the RS-485 network.
Warning:
⦁The 12V N+ and N- communication input must be supplied from only one point. Connections from more
than one 12V supply may cause failure or damage to the unit or the device supplying network power.
⦁The 330 ohm EOL (End of Line) resistor provided in the accessory bag must be inserted between the NA
and NB terminals of the first and last modules on the RS-485 network. These are the modules physically
located at the ends of the RS-485 network cabling.

Inputs
The input/output expander can monitor the state of up to 8 inputs. These inputs can be connected to a variety of
EOL monitored or dry contact devices such as magnetic switches and PIR motion detectors. Devices connected to
the inputs can be installed to a maximum distance of 300m (1000ft) from the module when using 22 AWG wire.
Each input may be individually configured for normally opened and normally closed configurations with or without
EOL resistors for tamper and short condition monitoring.
When using an input with the EOL resistor configuration, the controller generates an alarm condition when the
state of an input changes between open and closed and generates a tamper alarm condition when a wire fault
(short circuit) or a cut wire (tampered) in the line occurs.
When using the EOL resistor configuration, the EOL resistor option must be enabled in the input programming so
that the tamper and short states can be monitored. For more information, refer to your Protege programming
reference manual.
EOL Resistor Input Configuration:
Each input can use a different input configuration. To program a large number of inputs with the same
configuration use the multiple selection feature within the Protege software.When using the 'No Resistor'
configuration the controller only monitors the opened and closed state of the connected input device, generating
the alarm (open) and restore (closed/sealed) conditions.
No EOL Resistor Input Configuration:
Trouble Inputs
Each input/output expander can monitor up to 16 trouble inputs.
