Active production, redundant DP bundle
The 6ES7153-2AR03-0XA0: This is not a single IM 153-2 interface module; it is a bundle that typically includes the interface module plus the necessary bus connectors and possibly a power supply module, all in one orderable unit. The redundant configuration means two interface modules operate in parallel — if one fails, the other maintains the fieldbus connection to the CPU without a station dropout.
Sourcing and lead time
The UPC is 662643400953 — this is the retail barcode for the bundle, useful for warehouse receiving and inventory reconciliation against the Siemens packing slip.
