What the order code is
The 1TNE968900R1110 is a DIN-rail PLC expansion module listed at 0.09 kg, sized for one-handed handling at the cabinet and drop-in alongside an existing ABB PLC backplane.
Where this class lives in the stack
PLC expansion modules in this ABB line extend I/O and function onto a host PLC — typically clipping onto the backplane or sitting on the same fieldbus segment, so the only wiring concern at the panel is the bus drop and the field-side terminations, not the module mechanics. Because it is a PLCs and Accessories part and not a CPU, this code is normally ordered as a BOM adjunct to a host controller rather than as a standalone brain — specify it into the line alongside the controller order so the bus addressing and firmware revision stay aligned at startup.
Same-class siblings a buyer might cross-shop
Three peer order codes sit in the same PLC Expansion Modules sub-category at the same 0.09 kg weight on the listing — 1SBP260100R1001 and 1SVR440721R1000 — with one peer, 1SBP260104R1001, listed at 0.10 kg on the same line. Same-class match on category and weight is not a confirmed drop-in: before substituting any of those codes for 1TNE968900R1110 on a panel engineered around a different order code, the host-controller compatibility, bus profile, and terminal map must be checked against the host firmware.
Sourcing posture
The 1TNE968900R1110 is specified into the BOM on the printed order code, with no alternate or superseded designation in the title, and the title preserves the ASEA BROWN BOVERI legacy string — confirming the code still rides under the ABB part-number scheme.
