AVE presents the innovative 53ABR8 home automation multifunction actuator, a device that allows the management of lights (or stairway lights) and/or shutters (even with sunshade slat orientation) within the AVEbus system.

It’s an AVEbus multifunction actuator with installation on DIN rail (60715 TH35), where it occupies 6 x 17.5 mm modules. It’s equipped with 8 dry contact relays (with a capacity of 10 A 250 VAC), divided into four sub-devices, each with two freely programmable relays. Each of these sub-devices can perform the function of light or stairway actuator, roller shutter or shutter with sunshade slat orientation. In Light mode, the two relays are equivalent to two separate logic channels: Ch.xA and Ch.xB; instead, in Shutter mode, the two relays belong to the same logic channel Ch.x A/B, where A is the up contact and B the down contact (with interlock).

For each of the four relay groups, the operating mode is selected from the front of the device: after pressing PRG (to activate configuration mode), pressing button A sets the pertinent relay group to Light mode, while pressing button B sets it to Shutter mode. Light / Stairway Light or Shutter / Shutter with sunshade slat orientation are chosen through configuration from AVE Cloud App – EasyConfig or SFW-BSA.

Manual forcing is also available through the front control buttons. Pressing the button for a given relay causes that relay to switch manually and this is indicated as the pertinent LED goes on. In Light mode, it is equivalent to forcing the output into manual mode in which

commands from the bus are ignored until automatic operation is restored by either pressing AUTO or rebooting the device. In Shutter mode, forcing remains in effect for as long as the button is pressed.

The device is equipped with LEDs for feedback status: the green colour with slow flashing indicates normal operation, while fast flashing identifies the configuration; the steady amber colour warns of the relay switching, with a short pause it instead identifies manual forcing and with slow flashing it signals the configuration mode of the relative channel.

The 53ABR8 multifunction actuator represents a further added value for the AVE DOMINA Smart home automation system: through a single device it’s possible to manage two of the most requested functions, giving the installer more versatility and greater possibilities for home automation systems.
