Additional Measures; Power Supply Examples - WAGO 765-4203/0100-0000 Product Manual

Planning
Note
Note the following when L1 and L2 are supplied separately:
If L1 and L2 are to be supplied separately (e.g., for safe switch-off of L2), then either cen-
tral grounding must be implemented using two power supply units, or the power supply
connection must be made on the same phase. Use of two separate power supply units is
not mandatory.
Fuse Protection
Always protect the power supply lines from the power supply unit to the first module with
a device circuit breaker or fuse. For this purpose, use a 24 VDC / max. 16 A fuse or cir-
cuit breaker with type B trip characteristics.
Note
Device damage if maximum supply current exceeded
The maximum supply current must not be exceeded. Otherwise, there is a risk of damage
to the PCB of the device and the pluggable connector.

6.2.3 Additional Measures

The setup must ensure that the total current the flows back through pin 3 does not ex-
ceed the load limit.
The values of all currents on all pins of all connections (except for pin 3 = ground pin) and
the calculated total currents of the two supply cables are measured by the chip used in
the 765 Series products and thus can be recorded by a monitoring application. These val-
ues can be accessed via the OPC UA server, for example.
On the basis of these measured values, a monitoring application with integrated current
management can be implemented. This can regularly verify that all monitoring functions
are satisfied on the basis of the measured current values and also monitor the tempera-
tures and voltages on the connections.

6.2.4 Power Supply Examples

The product can be powered alone with its operating voltage or form part of a power sup-
ply group along with multiple products.
Power supply groups of multiple products can be formed in two ways:
1. Via the PWR OUT connection:
One or more additional products can be powered via the PWR OUT (X32) power sup-
ply output and then form a power supply group together with the product.
2. Through an IO-Link hub*:
One product forms a common power supply group with IO-Link hubs
(765-170x/0200-0000) connected via IO-Link.
* Only applies to modules with integrated IO-Link master ports
In what follows, we present one example for the 765-4204/0100-000 product with four IO-
Link inputs/outputs for each of the following:
• Individual power supply
