The ABB IO/S8.6.1.1 I/O Actuator combines 8 binary inputs and 8× 6 A switching outputs in one 8 MW MDRC for hotel rooms, apartments, and compact load panels. Bus-powered—no separate electronics supply.

Inputs can be linked internally to outputs or used as independent KNX binary inputs (window contacts, cards, push-buttons). Sister channel count: IO/S4.6.1.1 (4 in / 4 out).

Key Features

• 8× 6 A outputs: Lighting and small loads.
• 8 binary inputs: Dry contacts / push-buttons.
• Internal linking: Input→output mapping in ETS.
• Bus-powered: No auxiliary mains for the electronics.
