Information
The electrical isolation method correspond to EN 61800-5-1.
The following conditions apply for safety digital inputs of the D3-DA 3xx/x:
●
The inputs SDI00/SDI01/GND are isolated against SDI02/SDI03/GND.
●
All inputs are isolated against 24 V power supply.
●
All inputs are isolated against PE.
●
Maximum allowed isolation voltage: PELV
●
Maximum allowed input voltage: -60 V ... 60 V
