8PORT IOL-B FLD PN DC 24V 2.0A
• 1L to power the logic and sensors/actuators
• 2L to power actuators (separate actuator supply)
All supply voltages are connected via L-coded M12 pluggable connectors.

NOTICE
Damage to electronics
Connect each of the supply voltages (each to +24 V and 0 V) completely. Connecting
multiple supply voltages through one 0 V connection is not permitted, since this would ex-
ceed the current load capacity of the contacts.
Power Supplies 1L and 2L
The voltages 1L and 2L are electrically isolated and are fed in on connection X31.
The 1L power supply is required to power the module electronics and the connected sen-
sors/actuators. Connect it to connection X31. If you want to power additional products
through this current path, connect the cable for the additional power supply to connection
X32.
The following procedure is especially advantageous:
• Install the power supply for the module electronics independently of the power supply
for the actuators
• Provide independent fuse protection for the power supplies
This allows the network to continue to run even when peripheral parts are switched off.

NOTICE
Damage to electronics
The current load capacity of the L-coded M12 pluggable connector is 16 A per current
path (1L or 2L). This value must not be exceeded. To limit the sum of current paths 1L
and 2L even in the event of short circuit, it may be necessary to provide fuse protection
for them. For the calculation of the maximum permissible current feedthrough, see sec-
tion

.
Note that the connection for the additional supply voltage is not monitored for overload. If
the maximum current carrying capacity is exceeded, this can damage the pluggable con-
nectors.
WAGO recommends using pre-assembled cables.
Power supply 2L is provided to power actuators. It can be used by all products that re-
quire a second separate power supply with high power. It can also be passed on to addi-
tional devices.
The following figure gives an example of feeding in and passing on the supply voltages:
