1 USER GUIDE RLH Industries, Inc. The leader in rugged fiber optic technology. U5 08A00 hannel 0mA/00V Industrial Media onverter SYSTEM INSTALLATION INFORMATION Description This Fiber Optic Media converter transmits 0mA or 00VD signals over fiber cable. Offers high end specifications: 78,000 samples a second, 6 bit signal resolution, and less than 0.% source signal variance. ompatible with most PL's, Sensors (,, or wire), and other types of equipment where a precise current or voltage measurement must be taken and transmitted over fiber. The system comprises of a transmitter (Analog Input) and a receiver (Analog Output). Each device is enclosed in a compact DIN and wall mountable housing. This compact and rugged system provides convenient and easy to read LEDs, supports both singlemode and multimode fiber applications, and includes an alarm on either side monitoring system power and fiber health. Designed to operate over an extreme temperature range, providing reliability in harsh environments. It was designed and is made in the U.S.A and is covered by our Limited Lifetime Warranty. ~0mA System Extends up to separate analog 0mA current signals. 0mA signals are less susceptible to noise interference, can easily detect an open circuit, and current measurement remains the same in any point of the signal path. 0~0VD System Extends up to separate analog 00 Volt signals. Transport analog voltage signals over long distances without compromising accuracy and reliability. h.

2 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. aution 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. Guidelines for Handling Terminated Fiber able 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. ontamination will cause signal loss. Do not touch fiber ends. Store excess fiber on housing spools or fiber spools at site Acronyms ommonly used acronyms, terminology, and abbreviations.

3 " Applications By utilizing fiber optic cable, the ~0mA / 0~0VD system provides absolute electrical isolation between both ends of the control system. It provides immunity 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. Fiber optic cable also allows for a signal transmission of up to 0km over fiber optic cable from the source signals location. ontrol 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 alldielectric fiber optic cable (instead of copper) completely eliminates the presence of a remote ground, which dramatically increases signal accuracy, reliability of equipment, and safety of personnel.

5 Installation Prior to installation: heck for shipping damage. heck 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: VD power source at both installation sites. DIN rail for mounting, or wall space for wall mounting. Multimeter Measure the D voltage of the source power to ensure that it is VD. All electrical and fiber optic connections are made directly onto the unit.

7 onnect Fiber Optic able onnect fiber to the transmit and receive optical connectors on the front of the units. Fiber cable should always be routed loosely avoiding tight bends. For dual fiber systems connect the fiber port to the fiber port at the remote side. For single fiber systems ensure Side A is connected to Side B. Two side A devices will not pair together, the same applies to side B. Single fiber systems will always have a Side A & B. Once the system is properly connected the Link LED, on the receiver unit, should turn ON. onnect opper Wire Pairs The wire pairs from the sensor or controller equipment connect to the green screwdown terminals on the transmitter and receiver modules labeled Input and Output. Observe polarity on the input and output connectors. The contact terminals may be removed and accept wire sizes 6~6 AWG. Fully seat the terminal block back into the connector before operating the system. When using Wire devices ensure common terminals are connected. Alarm ontact Wiring The contact will alarm when the fiber link is down or a power failure. Use the NO or N contact positions as required. The alarm terminal block may be removed and accept wire sizes 6~6 AWG. Fully seat the terminal block back into the connector before operating the system. An alarm terminal is present on both the and. onnect Power Ensure power supply is OFF prior to wiring the system. Each device has redundant power input terminals. onnect a VD power supply to the screwdown terminals labeled PWR or PWR located on the top of the unit. Either pair of terminals or both may be used to power the device. Requires one () VD power supply on each side of the system. Fully seat the terminal block back into the connector before operating the system. Note: Power input is NOT polarity sensitive.
