Weed Instrument 2A56 Power Supply Техническое Руководство

Overview 
The modular EOTec 2000 fiber optic analog data link 

provides reliable, lightning immune transmissions of  

4-20mA and 0-10VDC signals over a single fiber optic 

cable.  It is an ideal solution for long run cable problems 

with 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. 

 

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). 

 

Applications for this device include long distance 

transmissions, lightning prone areas and transmissions 
through hazardous areas.
