Function description

•

4-fold FIX1 or 8-fold FIX2 switch actuator.

•

Up to 25 A switching current.

•

Connection cross-section up to a maximum of 6 mm

•

Energy-saving thanks to bistable relay.

•

No power connection required.

•

LED switching status indicator for each channel.

•

Manual operation on device.

•

Adjustable features: e.g. switching, delayed switching, pulse function.

•

Links, type of contact (NC contact/NO contact) and participation in central commands

such as permanent On, permanent Off, Central switching and save/call up scene.

•

Switch functions: e.g. On/Off, pulse, On/Off delay, staircase light with forewarning.

•

Logical links: e.g. block, AND, release, OR.

•

Activation of the channel function via 1-bit telegram or 8-bit threshold.
