Multiplexers
Multi-Node MX Multiplexer

  • The EOTec 2000 Multi-Node MX Multiplexer can manage up to 1024 inputs to an unlimited number of outputs of analog or digital electrical information, over a bi-directional pair of daisy-chain or self-healing ring fiber optic cables. Input/Output module selections include 4-20mA, 0-10VDC, and contact closures. The base unit connects directly to the fiber optic cable via Small Form-factor Pluggable (SFP) transceivers and provides visual indicators for power, global alarm, module status as well as the fiber link status. Each base unit has two optional transceiver ports supporting both 1300nm and 1550nm wavelengths for both multi-mode or single mode optical fiber. An integrated backplane allows for communications from the base unit to the input/output modules with no need for external inter-modular connections. No programming is required, as input/output configuration is derived via a one-time dip-switch configuration. Power is supplied through redundant external 24VDC power supply terminals. Applications for our Multiplexers include remote data acquisition, emissions monitoring, data and signal transmission, in lightning prone locations and hazardous areas, tank gauging, and conveyors.

MX Series Multiplexers
MX Series Multiplexers
  • EOTec 2000 Multiplexers can send up to sixteen channels of bi-directional electrical information over a pair of fiber optic cable. Input/Output module selections include 4-20mA, 0-10VDC, contact closure and RS-232/485. 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 input/output 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.
