4-Channel Contact Closure
Fiber Link Card System
Fiber Link Card Installation Information
Description
The 4 Channel Contact Closure Fiber Link system
provides a transmission of up to four independent
contact closure signals over one optical fiber. The
systems comprises 2 cards, a transmitter card and a
receiver card.
This hardened, rugged system is designed to be installed
into any of the RLH card shelf housings and is covered
by our Exclusive Unconditional Lifetime Warranty.
Contact Closure Transmitter Card
The Contact Closure Transmitter Card provides the
electrical/optical interface between the dry contact
closure relay input and a monitoring system or
equipment. The card is locally powered from a
24-56VDC source.
Note: In order to maintain high voltage isolation,
TX and RX Fiber Link cards must be powered from
separate power sources.
Contact Closure Receiver Card
The Contact Closure Receiver Card provides the optical/
electrical interface between a monitoring system or
equipment and a normally-open relay contact output. The
receiver card is locally powered by a 24-56VDC source.
The receiver card provides LED indicators to display relay
conditions, power, fiber carrier receive and fiber link
status.

General Safety Practices
The equipment discussed in this document may require tools designed for the purpose being described.
RLH recommends that service personnel be familiar with the correct handling and use of any installation
equipment used, and follow all safety precautions including the use of protective personal equipment as
required.
Caution - Severe Shock Hazard
•
Never install during a lightning storm or where unsafe high voltages are present.
•
Use caution when handling copper wiring and follow appropriate safety regulations.
Special handling requirements
Be careful when handling electronic components
ATTENTION
ELECTROSTATIC
SENSITIVE
DEVICES
•
This product contains static sensitive components.
•
Handle the cards at their edges only.
•
Follow proper electrostatic discharge procedures.
This card utilizes circuitry that can be damaged by static electricity. When transporting the card, carry it in
an ESD safe container such as the antistatic bag provided with the card. Before handling cards, discharge
yourself of static electricity by physical bodily contact with earth ground. When handling cards, hold by
outer edges and avoid touching circuitry. Failure to follow ESD precautions may cause serious damage to
the card and prevent proper operation.
Guidelines for handling terminated fiber cable
Page 2
•
Do not bend fiber cable sharply. Use gradual and smooth bends to avoid damaging glass fiber.
•
Keep dust caps on fiber optic connectors at all times when disconnected.
•
Do not remove dust caps from unused fiber.
•
Keep fiber ends and fiber connectors clean and free from dust, dirt and debris. Contamination will cause
signal loss.
•
Do not touch fiber ends.
•
Store excess fiber on housing spools or fiber spools at site

Applications
Network equipment in high voltage areas can be at risk due to Ground Potential Rise (GPR). A copper
network cable referenced to a remote ground can become a path for high voltages during a ground fault.
Placement of all-dielectric fiber optic cable (instead of copper) completely eliminates the presence of a
remote ground, which dramatically increases safety of personnel and reliability of equipment.
By utilizing fiber optic cable, the Contact Closure Fiber Link System provides absolute electrical isolation
between both ends of the network. It is immune to EMI/RF interference, ground loops, and high voltage
surges from lightning or ground faults, and is ideal in electrically noisy environments such as near large
power sources, electrical motors, and radio communications equipment.

Installation
Before Installing:
•
•
•
•
Check for shipping damage
Check the contents to ensure correct model and fiber type
Have a clean, dry installation environment ready
Ensure that the fiber type at the site matches the system type
Required for installation:
•
•
•
•
24-56VDC (15mA@24VDC minimum) power source at the TX side
24-56VDC (65mA@24VDC minimum) power source at the RX side
RLH card housing
Multimeter
Measure the DC voltage of the source power to ensure that it is 24-56VDC. All electrical and fiber optic
connection are made directly onto the card. The Fiber Link Card system is designed to be installed into
any RLH card housing.
Connect fiber optic cable
Connect fiber to the transmit and receive optical connectors marked FIBER TX and FIBER RX on the
faceplate. Fiber cable should always be routed loosely avoiding tight bends.
Connect copper wire pairs
Connect the wire pair from each dry relay contact to the green screw-down terminal on the faceplate. The
channels are listed as CH1 ~ CH4. Note which contact channel is being used.
Note: This system is dry contact only. Do not apply voltage to the contact terminals on the TX unit or the
system may be damaged.

Connect alarm relay monitoring equipment wire pair to the alarm contact marked ALARM. To make wiring
easier, the connector blocks may be removed from the card by pulling straight out. Seat the connectors
fully into their sockets before operating the system.
Connect Power
Connect a 24-56VDC power source wiring to the screw-down terminals indicated as DC POWER. The
power input is not polarity sensitive. To make wiring easier, the terminal unplugs from the card by pulling
straight out.
Set Alarm Jumper
The RX card includes an alarm contact for connecting to monitoring equipment. It monitors the fiber
signal from the TX side, so when the alarm is on there either a problem with the fiber cable and
connections, or the TX side is powered down.
The alarm contact is set at the factory to Normally Closed (NC) by default. To change the alarm contact to
Normally Open (NO) move the jumper on the card to the NO position.
