What it is
The R61012281: Lifecycle stage is current per the published line, so the part is specified into active BOMs rather than routed through last-time-buy or surplus channels.
Field note for the panel builder
A sub-kilogram PLC module of this class goes into a standard DIN-rail or backplane cut-out; the install cadence is the usual one — seat the module, lock the latch, address it via the rotary or DIP switch on the front, then map I/O in the engineering tool before any live wiring check.
