Inputs (control head –> IO-Link master/PLC) / Binary or analog
feedback signals:
T he recovery of the valve positions reported back in binary
format (S1 to S3 and S4) or the analog position signal is
described in the Operating Instructions in chapter "Position
measuring system". The analog target position signal (resolution:
0.1 mm) is available as cyclical value/parameter.

Electrical installation
WARNING!
Risk of injury due to electric shock!
` Before reaching into the system, switch off the power supply
and secure it to prevent restarting! Observe the applicable acci-
dent prevention and safety regulations for electrical equipment!
Risk of injury due to improper installation!
` Installation may only be carried out by authorised specialist
personnel and using the appropriate tools.
Type 8681 (IO-Link design) is offered in 2 versions:
• Port Class A: w ith shared power supply (Power 1) for
powering the system and actuators or
• Port Class B: w ith power supply (Power 1) for powering the
system and Power 2 for separately powering
the actuators, which enables only the actuators
to be shut-off for safety purposes.
