electrons occurs between the oxidised form and the reduced
form of an electrolyte. The resulting voltage is the oxidation
reduction potential.

The device automatically switches from büS to IO-Link according
to the master wired to it.
According to the master that is connected, the device LED, on
the top cover of the device, blinks orange at start:
• 4 times when a büS master is connected
• 2 times when a IO-Link master is connected.
After this, the device LED will indicate the NAMUR state of the
