Optimus 8-Channel Combined Actuator

The 8-channel Combined Actuator is the smallest member of the Optimus OPT-CA family, combining switching, shutter/blind, and fan-coil control functions in a single DIN-rail device. With eight freely assignable outputs it is sized for apartments, small villas, or a single zone of a larger project — one compact actuator where separate switch and blind actuators would otherwise be needed.

Every channel can be configured in ETS as an independent 16A switching output or paired for blind/curtain control, and the integrated logic covers staircase timing, scenes, and manual override. When a project outgrows eight channels, the same family scales without re-learning anything: the 20-channel model covers mid-size distribution boards and the 24-channel version anchors full-floor panels.
