Y-cable
The Y-cable allows you to connect two actuators or sensors to the inputs or outputs.
The use of a Y-cable is particularly recommended when two channels are occupied for each
socket of an I/O device. The Y-cable distributes the channels to two circular connectors.
• Y-cable (6ES7194-6KA00-0XA0) for connecting 2 actuators or sensors for double
connection of inputs (also fail-safe inputs) or double connection of outputs with one cable
• Y-cable (6ES7194-6KB00-0XA0) for connecting 2 sensors for double connection F-DI with
one cable. Only suitable for use with the F-DI module.
You can find details about connection in the respective user manual of the product.
