Manufacturer device scope

IO-Link input/output device, requiring a Class B master port; not an IO-Link master. COM3, minimum process cycle 4 ms; SIO mode not supported.

Manufacturer I/O scope

16 total I/O; 16 digital input, 16 digital output and 8 analogue input capabilities depend on configuration, not 40 simultaneously available channels. Analogue input selectable 4–20 mA or 0–10 V, 16 bit.

Manufacturer output scope

1.8 A maximum per output and per segment; 3.6 A total output current. Segment and total limits still apply; supply UA 18–30 V DC.

DeviceID scope

1405 cyclic parameterisation is factory mode; 1406 is acyclic parameterisation. Verify IODD/device revision before commissioning.

Manufacturer protection scope

IP65 / IP67; IP69K operation requires stainless steel protective caps.
