In the 1 x 4 byte version, up to 4 connecting cables can be connected to the front connector modules for digital 16-channel or 32-channel modules. In the 1 x 4 byte connection version the connection is made with just one pre-assembled connecting cable. These are connected to the terminal modules.

A connecting cable with a 2-ampere terminal module in each case is connected to the front connector modules for 2-ampere output modules.

In the case of the front modules for the analog I/O modules there are versions got connection with four connecting cables (16 pole) or one connecting cable (50 pole).

The potential can be fed in at the terminal module or at the front connector module in the case of the 16/32 digital I/O modules:

Potential infeed via the front connector module with plugged-in jumper on the front connector module:

• Max. current per double byte at 60°Celsius: 4 A
• Max. current per double byte at 40 °Celsius: 6 A

Potential infeed via the front connector module without plugged-in jumper:

• Max. current per byte at 60 °Celsius: 2 A
• Max. current per byte at 40 °Celsius: 3 A

If full current load is required, infeed must be implemented via the terminal modules. Potential infeed via the terminal modules without plugged-in jumper on the front connector module:

• Max. current per byte at 60 °Celsius: 3 A
• Max. current per byte at 40 °Celsius: 4 A
