maximum distance for dc signal
Are there any document for the distance of dry contact signals?
As refering to Siemens PLC catalogue, maximum distance of digital input and output are 1000m ( for shielded cable) 600m ( for unshielded cable).
but any information for relay (24VDC) could not be found.
Thank in advance.
