Fiber optic analog/digital link
Weed Instrument
The modular EOTec 2000 fiber optic analog data link provides reliable EMI/RFI and lighting immune transmissions of 4-20mA and 0-10VDC signals over a single fiber optic cable. It provides a robust solution for the problems typically found with long run cable runs and features a system accuracy of 0.1%. Each transceiver has a single optical port for use with multi-mode or single mode optical fiber at 850 nm or 1300 nm using industrialized ST/SMA connectors. Optional external indicators are available for local monitoring of the input/output signals.
Applications for this device include long distance transmissions, lightning prone areas and transmissions through hazardous areas.
Power supply option
The FOT/FOR will accept power from a 120/240VAC power source when using the EOTec 2A56 power supply, or from an external 24VDC power source connected directly to a screw terminal (shown using both configurations in the above photo).
