Supply concept
CAUTION
Product damage when the permissible leakage current is exceeded.
Product damage and/or damage to other connected products if the maximum permissi‐
ble leakage current is exceeded.
In addition, observe the derating, i.e. the maximum current depending on the ambient
temperature.
Voltage supply
The 24 V voltage supply is fed in via port PWR1. The maximum current carrying capacity
of the module is 16 A. The module has two supply lines, which are
not galvanically
isolated
:
•
Supply line 1 (US) connects 1L+ (pin 1) to L- (pin 3).
•
Supply line 2 (UA) connects 2L+ (pin 4) to L- (pin 2).
Subsequent modules can be supplied with power via the PWR2 port. This leakage
current must be taken into account when designing the supply. The total leakage
current is limited to 16 A.
Sensor supply
The devices connected to the module are supplied via IO-Link ports S1 – S8. When
designing the supply, the requirements of the connected sensors and actuators must
be taken into account. The maximum current for the supply of all connected devices is
limited to 10 A.
The maximum current per port is <= 4 A. The upper limit for the current on the
individual pins of IO-Link ports S1-S8 is:
