The Siemens 6ES7321-1BH02-4AA0 is an S7-300 IO-Module Bundle, a pre-assembled grouping of input/output hardware for the S7-300 rack. It draws 7 mA from the backplane bus and dissipates 3.5 W typ. This is a bundle, not a bare module — it ships as a matched set, which saves panel-build time on a new install but means you replace the whole assembly if a single channel fails.
