Planning
– Rule 1: Take maximum load capacity of each connection contact (pin) into ac-
– Rule 2: Take 1L and 2L current feedthrough into account
• Ports X01, X02 etc.
– Rule 3: The current load of pin 3 must not exceed 4 A, since the sum of the pin 1,
Rules 1 and 2: Supply Input X31 and Output X32
The currents for the electrically isolated supply cables 1 and 2 should be considered sep-
arately. The two supply cables 1 are defined as follows:
• Supply cable 1 corresponds to the current flow path that starts from pin 1 (signal 1L+)
of supply voltage connection PWR IN (X31) and passes through the device to pin 3
(signal 1L-) of PWR IN. This is shown in blue in the current flow figure under
nect Sensors/Actuators
• Supply cable 2 corresponds to the current flow path that starts from pin 4 (signal 2L+)
of supply voltage connection PWR IN (X31) and passes through the device to pin 2
(signal 2L-) of PWR IN. This is shown in red in the current flow figure under
nect Sensors/Actuators
The following rule applies to both supply cables:
Rule 1 – Upper limit of 16 A for current in the entire supply cable (1L or 2L)
An upper limit of 16 A applies to the total current in a supply cable. If this upper limit is ex-
ceeded, there is a risk of destruction of or damage to the module. To avoid this, protect
each supply line with a fuse or circuit breaker. Read

Also observe the derating, i.e. the maximum current as a function of the surrounding air
temperature. Read
The following partial currents contribute to the total current in supply cable 1:
1. The I
via supply cable 1)
2. The I
each port i)
3. The I
other connected devices (current feedthrough)
The following partial currents contribute to the total current in supply cable 2:
1. The I
each port i)
2. The I
other connected devices
The following rule applies to both supply cables:
Rule 2 – Current feedthrough limiting
The supply voltage for the devices of a supply cable that are connected to PWR OUT the
output supply connection is passed on through the device via the input supply connec-
tion. The maximum permissible current feedthrough for the respective supply cable is de-
