I/O Connection Diagram

Connection of a dry contact sensor to the DI module requires "wetting" the contact with a
voltage. This can be done using the 24V DC floating plug-in power supplies that can be added
to the module (in 16/32 DI Fast 24V/ Fast 24V IEC TYPE 2 modules only). The 24V can be
also used to power "wet" sensors.
