BMX-SDI-1602 Safety input module

[Marinero]

Hello everyone,

Was wandering if anyone can explain to me or help me to better understand the wiring diagram. So for some schematics I am checking right now, I have an e-stop wired via 2 inputs, connected on pins 2 and 10 of safety card. The next pair goes to pin 4 and 12, next one for 6 and 14 ecc. I know that for siemens safety cards dual channels are usually 0,4 then 1,5 ecc but I am not able to find for the Schneider module this analogy. So for Siemens channel 0,4 would be 1,9 or 2,10 for Schneider module or am I wrong? I don't know how clear I am, if something is not clear please don't hesitate to correct me. 

Thanks for your help in advance!
