BLUMOTIX BX-RO8 KNX M-DIN 4/8 OUT multifunction actuator (16A)

The BLUMOTIX BX-RO8 is an 8-channel multifunction actuator, designed for mounting on a DIN rail and intended for independent switching of loads using relay contacts.

Key Features

The BX-RO8 actuator is equipped with 16 A bistable relays, which allow you to control general loads, raise and lower shutters and blinds, control valves with PWM drive and manage fancoils with 2 or 4 tubes.

Control functions

• Output switching is also managed through the buttons on the front panel.
• Green LED to indicate channel status.
• Timing, forcing, blocking and delay functions.
• Management of roller shutters and venetian blinds.
• Valve piloting with PWM algorithm.
• Fan coil control with 2 or 4 tubes, from 1 to 3 speeds depending on the configuration.

Technical characteristics

• KNX bus connection: removable 2-pin terminal (d=0.8 mm).
• Electrical connections: screw terminal, max cable cross section 2.5 mm2 (AWG12).
• Degree of protection: IP20.
• Dimensions: 4 DIN modules.
• Nominal relay contact voltage: 230 V ac, 50/60 Hz.
• Nominal current of the relay contact: 16 A.
• Power supply: via KNX bus, 29 V dc SELV.
• Current absorbed by the bus: max 17 mA.
• Operating temperature: -5 ÷ +45 °C (indoor use).

Logical and General Functions

• Logical function set consisting of 16 input communication objects for each channel.
• Logical operations that can be combined with OR, AND, XOR and GATE.
• Can be parameterized by the ETS software.

The BX-RO8 actuator is particularly suitable for distributed design and can manage all the operations necessary for the management of a residential or tertiary building with a single device.
