[X20] digital outputs
NOTICE
Material damage or loss of function due to incorrect I/O circuitry.
• All digital inputs/outputs are designed as PNP. Use only corresponding circuitry.
–
The digital outputs are configured in 2-wire connection technology.
–
The digital outputs are galvanically isolated.
–
The current load for each output is 0.5 A.
–
The ground potential for all outputs relates to GND of the power supply [X5].
–
The digital outputs are protected against short circuit and thermal overload.
–
Use 2 adjacent terminals to connect a consumer.
