Optical LIN bus connection for explosion-risk areas

This can be used to substitute a segment of the electrical LIN bus by fibre optic cable. A PLIN-LWL set contains two converter modules and a duplex FO cable with standard ST connectors.

The electromagnetic compatibility of a converter module can be optimised by hardware configuration. At bit rates of up to 10.4kbit/s, an electrical LIN transmission is possible with signal edges being less steep. Another measurement to improve EMC is the use of the implemented linear voltage regulator (instead of the switching regulator) for input voltages up to 20V. A converter module is supplied either via the low voltage input (e.g. for the supplied mains adapter) or via a separate pin on the D-Sub connector.
