• The 3 plug-in connectors for the digital inputs and outputs are 50-pin terminal posts for
connecting ribbon cables.
• Terminal strip converters can be used, or the direct connection of distribution boards, for
example, is possible.
An external power supply unit (24 V DC) is required to supply the module and the digital outputs.
