5.2 Connecting the AS-i bus
Pin assignment of
AS-i interface
Connection must be made via the Festo AS-i
cable socket with a yellow AS-i flat cable
(protected against incorrect polarity by
mechanical coding). Use a power exclusively unit
with reliable isolation (low voltage es per PELV)
as per IEC-64 (e.g. Festo AS-i combi-power unit
part no. 18949).
Current consumption approx. 25 mA + current
consumption of sensors (max. 60 mA).

Always supply the valves separately with 24 V
operating voltage. Power supply via the AS-i bus
is not possible. Use a power unit with reliable
isolation (low voltage es per PELV) as per
IEC-64 (e.g. Festo AS-i combi-power unit part
no. 18949). Connect the power unit to the Festo
AS-i cable socket with a black flat cable.
Current consumption approx. 200 mA per output
(max. 5 W per output).
5.4 Connecting the sensors (positive switching, pnp)
Pin assignment of
M12 interface
Current consumption of sensors
(max. 2 x 30 mA):
see manufacturer specifications.
Pin assignment of sensor connection (pnp):
1 = + 24 V
2 = IN-2
3 = OV
4 = IN-1
5 = Earth/Ground
