Power Supply of the Module and the Connected Sensors/Actuators
The 24 V power supply is fed in via the X31 (PWR IN) supply input. The module has two
electrically isolated supply cables.
• Supply cable 1 connects 1L+ (pin 1) to 1L- (pin 3).
• Supply cable 2 connects 2L+ (pin 4) to 2L- (pin 2).
The sensors, actuators or hubs are powered through ports X01, X02 etc. The design of
the power supply must take the demand of the connected sensors and actuators into ac-
count.
Successive devices can be powered through the X32 (PWR OUT) supply output. This
current feedthrough must also be taken into account in the design of the power supply.
Protective Functions
The module has integrated protective functions (see section
[} 26]) to prevent damage in overload situations such as overcurrent or short circuit.
However, it is important not to rely on these protective functions alone, but also to limit
the currents externally,
because these protective functions do not cover the currents feedthrough for powering
successive devices through the supply output (X32). The maximum current for the current
feedthrough through X31 and X32 must be limited through fuse protection (see
datasheet), which must take their own individual consumption values, including that of the
connected loads of the connected modules, into account.
Consumption
For each supply cable, it is necessary to take into account the consumption that depends
on the connected devices.

• Logic supply (about 200 mA)
