How does PLC systems cabling work?
Wiring with the system cabling considerably reduces the assembly time and guarantees protection against polarity reversal. The first part of the systems is the card adapter. These front adapters with an integrated male ribbon cable connector (IEC 603-1 / DIN 41 651) are plugged onto the PLC I/O card. In order to plug in the adapter the original hard-wire swing arm must be removed from the card to expose the connection points for the plug adapter. The second part of the system is the field interface board. These interface boards are simply snapped onto the mounting rail instead of modular terminal blocks or coupling modules. On the control side they also have a multi-position male connector (ribbon cable type). The interface boards are connected to the front adapters using multi-position and preassembled system cables.
