For Modicon Premium automation platform, how are the IOs ( Sensors, switches...etc.)connected to the discrete IO modules?
This depends on the type of the discrete IO module selected. There're modules that are connected with screw terminals, other modules are connected via HE10 connectors.
For modules connected with screw terminals, customer will have to order the 20-way screw terminal block ( TSX BLY 01 ) to connect the IOs directly ( hardwire ).
As for modules connected via HE10 connectors, customer will also have to order an additional reference depending on whether the IOs will be connected to the module directly or not.
For direct connection, customer will need the 20-wire preformed cable ( reference is selected according to the length required ).
For indirect connection, there're the optioms of ( rolled ribbon connecting cable ) or the regular connecting cables. The choice depends on the diameter of the cables required.
