Analog/Contact Closure Fibre Optic Link

DIN rail Analog/Contact Closure Fibre Optic Link is a product designed especially for industrial applications.


The units may be used for transferring analog signals of +/-10V or 4-20mA current loop signals, together with contact closures over optical fibres up to 100 km. 


Up to 16 Analogue Input/ Output and 32 Digital Input/ Output available.


The links can also be ordered:

- with internal differential amplifiers, with gain of 1 - 100

- The digital inputs are 0 to 5V (TTL level), 12V, and 24V

- Transfer of RS-232 and RS485 

- 10A relay outputs

- Unidirectional or Bi-directional

- Single mode or multimode



Common applications:

* Transfer I/O and analogue of long distances (between substations, sensors to PLC, PLC to PLC)

* Transfer of signal through noisy environment
* High Voltage Isolation and Signal Isolation

* Mining and Train Remote Signals
* Elimination of Ground Loops
* Data Acquisition from remote sites
* Medical applications
* Nuclear applications
* EMI/RFI test chambers
* High pressure chambers
* 4-20mA or 0-20mA current loop interface
