HelloNagul, First, the6ES7153-2AR03-0XA0 is a Red.(undancy) Bundle. It includes 2 of IM153-2 HF and one active bus unit. You don't need this bundle as long as you don't have a redundant controller. So, you can compare between 6ES7153-2BA02-0XB0 and 6ES7153-1AA03-0XB0. The IM153-1 has some limitations regarding it's I/O capacity. The IM153-2 can have 12 modules with 244 bytes of I/O while the IM153-1 can have only 8 modules with only 128 bytes of I/O. So, if your remote I/O stations will not violate the limit of 8 modules and 128 I/O byte, then you can use the IM153-1. Best regards. H-H
