What this order code actually is
The ABB 1TNE968900R0110 is catalogued as a programmable logic controller under the PLCs & HMIs / PLCs and Accessories / PLC Expansion Modules class, with the title field carrying the same designation under the ASEA BROWN BOVERI brand string. The line description reads "PROGRAMMABLE LOGIC CONTROLLER by ASEA BROWN BOVERI," which is the only role-defining statement on the spec sheet — anyone specifying this code is committing to a controller-class slot, not a passive backplane accessory. Listing weight is 0.38 kg, well within the range that drops onto a standard DIN rail without panel-reinforcement work; for a panel-builder this is a one-man lift and no extra bracing is implied by the mass figure alone.
Because there is no L*-anchored successor on file, no official replacement order code can be named; sourcing has to be specified against 1TNE968900R0110 itself, not against an ABB-published cross-reference.
Same-class siblings on file
Three peer order codes sit in the same PLC Expansion Modules slice — 1SVR040013R2701 at 0.17 kg, 1SVR427071R0000 at 0.86 kg, and 1SAP120600R0071 at 0.13 kg — and none of them is presented in evidence as a same-function alternative to 1TNE968900R0110, so they are recorded as class siblings only, not as cross-shop candidates.
