What this module is on the expansion bus
The ABB 1SVR427075R0000 is a control module classed as a PLC expansion module under the ABB PLCs & HMIs line. It ships in the family of thin slice-side modules that sit beside the central rack or remote I/O island rather than inside the CPU base, so it inherits the standard PLC accessories slot mechanical footprint for the class. At 0.04 kgs it is one of the lighter entries in its class — for a panel builder, that translates to a single-DIN-module equivalent that does not need its own mounting plate or extra gland support; the weight is below the level where handling drives a lift plan or a cabinet reinforcement decision.
How it sits against the heavier sibling
Against ABB 1SVR427071R0000 the seed weighs 0.04 kgs versus 0.86 kgs on the same PLC expansion module category; the two share the product class but the weight delta says no drop-in slot swap.
