Analog Transmitter Card The transmitter card provides the electrical-to-optical interface between four independent analog 4~20mA or 0~10VDC inputs and a fiber strand. Each channel may be selected for 4~20mA or 0~10V signal protocols. The transmitter requires a 22-56VDC local power source for operation, and has an LED for power status.
General Safety Practices ..................................2
Note: The transmitter card may be configured for use with 0~5VDC or 0~20mA signals. Consult RLH for additional information.

Analog Receiver Card The receiver card provides the optical-to-electrical interface between a fiber strand and four independent analog 4~20mA or 0~10VDC outputs. Each channel may be selected for 4~20mA or 0~10V signal protocols. The receiver card requires a 22-56VDC local power source for operation, and has LED indicators to display power, alarm, and fiber link status. Note: The receiver card may be configured for use with 0~5VDC or 0~20mA signals. Consult RLH for additional information.

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 Fiber Link cards at their edges only.
•
Use only with RLH Fiber Link Card housings
•
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
"
•
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

Connect fiber optic cable Fiber Link Contact Closure Cards are equipped with an optical connector. Connect the fiber cable between the Transmitter card marked “TX” and Receiver card marked “RX” optics. Fiber cable should always be routed loosely avoiding tight bends.
Connect copper pairs Connect the wire pairs from the sensor or controller equipment to the green screw-down terminals on the Transmitter and Receiver Cards labelled CHANNEL 1 through CHANNEL 4. Observe polarity on the input and output connectors.
Connect Power Connect a 24-56VDC (15mA minimum) power source to the black “AUX. P.S.” screw-down terminal on the Card. The power input is not polarity sensitive.
Configuration The Transmitter card can accept 0~10VDC or 4~20mA inputs and the Receiver can output 0~10VDC, 2~10VDC, or 4-20mA signals. Each channel can be set individually. Refer to the following set up information:
4~20mA in and 4~20mA out (Factory Setting) •
Set switch labeled CH1, 2, 3 or 4 (SW1, SW2, SW3, SW4) on both cards to 4-20mA
•
On Transmit card, set Range Limit jumper (J3, J4, J5,J 6) to “B”
0~10VDC in and 0~10VDC out •
Set switch labeled CH1, 2, 3 or 4 on both cards to 0-10V
•
On Transmit card, set Range Limit jumper to “A”
4~20mA in and 0~10VDC (or 2~10VDC) out •
Set switch labeled CH1, 2, 3 or 4 to 4~20mA on Transmit card, then set Range Limit jumper to “B”
•
Set switch CH1, 2, 3 or 4 to 0~10VDC on Receive card
Note: The Receive card’s output may be set to 2~10VDC instead of 0~10VDC by changing the Transmit card’s Range Limit jumper to the “A” position.
0-10VDC in and 4-20mA out •
Set switch labeled CH1, 2, 3 or 4 on Transmit card to 0~10VDC, Range Limit jumper is set to “A”
•
Set switch CH1, 2, 3 or 4 to 4~20mA on Receive card
Troubleshooting If trouble is encountered, verify all installer connections, signal and voltage levels. If trouble persists, replace the unit and retest. If technical assistance is required, contact RLH Industries, Inc. Technical Support.
