The EOTec 2000 Fiber optic modems are a family of modules designed to take traditional copper networks, convert them to fiber optic signals, and convert them back again. All modules fit on standard 35mm DIN rail and each has an integrated backplane. As a result, there is no separate backplane to purchase and no external wiring between modules. Simply attach each module to the DIN rail and slide them together until they mate to one another. The EOTec 2000 series represents an extremely flexible and scalable solution to the problems often encountered when using copper to interconnect communication nodes. Both multi-mode and single-mode fiber optic links are supported. Options are available to support all the popular fiber optic connectors (ST, SMA, SC), providing users the ability to construct dependable and robust networks. Problems such as ground loops, isolation and lightning strikes are eliminated with the EOTec 2000 fiber optic modems. Fiber optic communication links can also be extended over much greater distances and take on physical topologies not available with copper networks. For instance, star and self-healing ring topologies are impossible when using copper interconnects. These configurations are easily achievable with the EOTec 2000.
EOTec 2000 Multiplexers can send up to sixteen channels of bi-directional electrical information over a pair of fiber optic cable. InputOutput module selections include 4-20mA, 0-10VDC, contact closure and RS-232485. The base unit connects directly to the fiber optic cable and provides a visual indication of the fiber link status. Each base unit has a duplex optical port configured for use with 1300nm wavelength, multi-mode or single mode optical fiber. An integrated backplane allows for communications from the base unit to the inputoutput modules with no external inter-modular connection. No programming is required. Power is supplied through an external 24VDC power supply. Applications for NSPI fiber optic Mulitplexers include remote analog data acquisition, Continuous Emissions Monitoring Systems at coal fired power plants, data transmission on wind turbines and signal transmission in lightning prone locations and hazardous areas. MX Multiplexer Base Unit supports up-to 16 channels IO Modules are available in 2 and 4 channel versions Maximum number of IO modules per optical side – 4 Maximum number of IO devices per optical side – 16
A thermocouple consists of two dissimilar metals, joined together at one end. When the junction of the two metals is cooled or heated a voltage is produced that can be correlated back to the temperature. Most thermocouple alloys are commonly available as wire. Thermocouples are manufactured in different combinations of metals andor calibrations. The calibrations most regularly specified by NSPI customers are J, K, T and E. High temperature calibrations include R, S, C and GB. Each calibration has a different temperature range and environment, although the maximum temperature varies with the diameter of the wire used in the thermocouple. While the thermocouple calibration defines the temperature range, the maximum range will also be a factor the diameter of the thermocouple wire. Therefore, a very thin thermocouple may not reach the full temperature range. Since thermocouples measure wide temperature ranges and are relatively rugged, they are very often used demanding industrial automation and process control applications. In selecting a thermocouple, the following criteria are key considerations: Temperature range Chemical resistance of the thermocouple or sheath material Abrasion and vibration resistance Installation requirements (may need to be compatible with existing equipment;existing holes may determine probe diameter)
Connection heads are available in cast iron, epoxy coated aluminum, stainless steel and polypropylene. For hazardous area applications, connection heads which comply with FM, CSA or ATEX standards can be supplied. Most of the housings meet or exceed NEMA 4 (IP 67) environmental specifications and can be used with virtually any NSPI RTD or thermocouple. As standard, each connection head is supplied with an integral terminal block to simplify field wiring. Alternatively, one of our economical Temperature Transmitters can be installed and preconfigured prior to shipment to complete your assembly.
NSPI manufacturers a wide variety of nuclear qualified thermowells in virtually any style or material. While NSPI’s standard thermowells are fabricated from stainless steel, other materials such as Monel, Inconel and Hastelloy are regularly produced. For ASME SECTION III compliant thermowells, we source bar stock materials from a certificate holder and then manufacture the wells under our NQA-1 and NCA 3800 quality program. The thermowell styles offered by NSPI include standard and heavy duty in socket wells, threaded wells and flanged wells.
The modular EOTec 2C20 Electrical Interface Module is designed for use with various Optical Interface Modules and Power Supply Modules within the EOTec 2000 product family. Various combinations of modules can be used to create many different network topologies using coax cable or glass fiber cable. Topologies supported include Point-to-Point, Daisy Chain, Star and Cascading Tree.
he EOTec 2000 fiber optic Multi-Channel Contact Closure transceiver modules are used to convert up to ten contact closure inputs into fiber optic signals for transmission over a single fiber optic link.
