Overview
Expansion I/O cards
If the 24 standard inputs and 16 outputs are not enough and you do not want to set up a fieldbus network, 24 inputs and 16 outputs per card can be added to your system. You can use a total of up to two expansion cards.
24 In, 16 Out
• 24 inputs and 16 outputs for every expansion card (up to 2 expansion cards for a total of 72 inputs and 48 outputs)
• Optical decoupling of I/O cards
• Protection against external influences such as overload or electrostatic discharge
