If yes, then which module is having this facility?  I want to take 8 digital i/p's as a sink type and 8 digital i/p's as a source type. Please suggest.

A set of 8 interfacing relays can be used to condition your sink inputs and allow you to proceed with your program. You are limited to 24 inputs remember.

This type of LOGO! supports 24V DC or 24V AC as power supply. If sink or source depends on how you wire it (Power supply and inputs). This is also possible with the LOGO! DM8 24R. Hope this helps
