Optical fiber multiplexer
Weed Instrument

NSPI manufactures modules for 4-20mA, 0-10V, RS-232 and contact closure applications. The base unit (or brain) connects to the fiber optic cable and provides visual indication of fiber link status. Information is received from up to four input modules that can be cascaded. Each module has a partner module installed on the corresponding base unit. An integrated backplane allows for communications between modules with no external inter-modular connection. Installation and commissioning is fast and simple -- no programming is required.

Typical applications:
Typical applications include remote analog data transmission over long distances, smoke stack emissions monitoring instrumentation, windmills (wind turbines) and extensions of DCS or PLC systems. Each base unit has a duplex optical port for use with multi-mode or single mode optical fiber with transmissions at 1300 nm using industrialized ST/SMA connectors.
