Hello MBSYSTEMS, There will be no problem with 1mm or even 0.5mm specially there's no high current will follow through the wire I am sure. It looks that that DI is for an Emergency button or a limit switch. So the current that will follow through the cable is equal to few milli Amps. But I recommend to use a separite small power supply for this input and use a relay near the module to energize the input. Back to your last question. There will be no problem with 900 m You can use up to 600 m for un-shield cables & 1000 m for shielded cables. Please check the technical specification of your DI module. You will found it in Module data. |
