Planning
Example of a Power Supply Group with an IO-Link Hub
Connection Example 1
In what follows, we consider a power supply group consisting of a 765-4102/0100-0000
IO-Link Master and a 765-1701/0200-0000 IO-Link Hub. The two products are connected
via IO-Link.
Three devices are connected to the 765-4104/0100-0000 module:
• On port X01: the 765-1701/0200-0000 IO-Link Hub
• On port X03: one digital input/output with max. current consumption of 2 A (on pin 1)
• On port X04: one digital input/output with max. current consumption of 2 A (on pin 1)
Four devices are connected to the 765-1701/0200-0000 IO-Link Hub:
• On port X01: one digital input/output with max. current demand of 1 A (on pin 1)
• On port X02: one digital input/output with max. current demand of 1 A (on pin 1)
• On port X03: one digital input/output with max. current demand of 0.5 A (on pin 1)
• On port X04: one digital input/output with max. current demand of 0.5 A (on pin 1)
The current consumption of each of the two WAGO 765 Series products is 0.2 A.
Since the 765-1701/0200-0000 IO-Link Hub gets its operating voltage from the
765-4104/0100-0000 IO-Link master, port X01 (pin 1) of the module has a load of 3.2 A =
1 A + 1 A + 0.5 A + 0.5 A + 0.2 A, which is below the maximum load capacity of 4 A and
thus permissible.
Port X02 is unused.
Ports X03 and X04 each have a load of 2 A, which is also below the maximum load ca-
pacity of 4 A and thus permissible.
Connection Example 2
Now we increase the current consumption on the two ports X01 and X02 of the
765-1701/0200-0000 IO-Link Hub to 2 A and check whether this is permissible:
The ports of the 765-1701/0200-0000 IO-Link Hub can withstand a constant load of 2 A.
However, the effects on the 765-4102/0100-0000 product must be considered.
