Optimus 20-Channel Combined Actuator

Positioned between the compact 8-channel and the flagship 24-channel models, the 20-channel Combined Actuator is the workhorse for mid-size distribution panels — a typical villa floor or a cluster of hotel rooms where lighting circuits, curtains, and fan-coils are controlled from one board. Twenty freely assignable outputs mean one device can replace two or three single-function actuators, saving DIN-rail width and wiring time.

Functionally it mirrors the rest of the OPT-CA family: each channel works as a 16A switching output or pairs up for blind control, with ETS-configurable scenes, logic, and staircase functions, plus manual override buttons on the front for commissioning and maintenance. Pick the 8-channel for small zones, this 20-channel for standard floors, or the 24-channel when maximum density per panel is the priority.
