TIOL111: Conducted immunity - IEC 61000-4-6

Part Number: TIOL111

Hello community,

Does anyone know if the TIOL111 IO-Link transceiver needs additional external components (filters) to comply with IEC 61000-4-6 conducted immunity?

It will be used as an IO-Link device with a compliant stack.

Is there a design guide I've missed?

Thanks

Paul

    Hi Paul,

    I'm not aware of any IEC 61000-4-6 testing that has been conducted on this device, but I would not expect external filtering to be required. I say this because external filtering was not found to be needed when testing against IEC 61000-4-4, which generally presents a higher stress on the interface line. (The IO-Link Interface and System Specification states that IEC 61000-4-6 is mostly expected to influence the EUT's analog signal processing and would only have a very small probability of affecting the serial communication.) A conservative approach, though, may be to include pads for series and shunt components so that filtering can be added later if found to be needed (assuming there is enough space available).
