What the listing carries
The ABB 1SDA060397R1 is filed as a PLC Expansion Module under the ASEA BROWN BOVERI product line, and the on-record functional figure is a 110.125 VAC/DC rating tagged T6 — the one spec a panel builder needs to confirm the supply envelope before it goes on a DIN rail or into a breaker accessory pocket. The headline number to anchor a BOM line is 110.125 VAC/DC (T6): that voltage window is the decision, not a footnote, because a mis-matched coil or release voltage is the most common way a spare sits in the drawer and never makes it into a cubicle. Mass is 1.54 kgs — meaningful for one-handed handling on a live swap, but it is not a selection parameter; choose on the electrical rating, not the grams.
Cross-shop against a sibling order code
The lighter siblings on file — 1SVR040013R2701 at 0.17 kgs and 1SAP120600R0071 at 0.13 kgs — sit well outside the 1.54 kg mass envelope of 1SDA060397R1, which by itself rules them out as a like-for-like swap on a panel that was laid out around the heavier part.
