ABB TruOne I/O expansion module, 2 digital inputs / 2 digital outputs, PLC Expansion Module class, order code 2K-1-OX, listed at 0.23 kg.

| Weight | 0.23 kgs |
The ABB 2K-1-OX is a TruOne I/O expansion module carrying 2 digital inputs and 2 digital outputs, and it is the same part listed in the PLC Expansion Module accessory line for ABB PLCs. It populates a DIN-rail or backplane slot alongside the controller and is specified to extend a small I/O count where adding a full slice would overshoot the budget on the base unit.
No swap is asserted: 3BSE013237R1 is a same-class ABB PLC Expansion Module at 0.17 kg, but it is not shown here as a direct functional alternate, so the panel's existing wiring and addressing need to be confirmed against each module's own pinout and configuration before any substitution.
