GX I/O Extender manual is missing

Hey,

there is no manual available, and the device doesn’t works as expected.

I put a voltage divider and a Z-diode to the digital io for protection.
I have 4.1v at the input, but the node switch in node red is still off /0.
The switch is set off, so the I/O should be an input.

Any ideas?

Best Lars

The manual is now online on the product page:

Please put the input and output circuit schematic to your PDF.
Please design outputs short circuit proof and inputs with optocouples like every PLC is doing this.
