The SK08-Ventil4 is a surface-mounted KNX control unit for up to four valve actuators or mixing valves in heating and cooling systems. Each output drives a proportional valve with 0-12 VDC or a thermal actuator with 24 VDC PWM, and the built-in controller modes let it regulate zones directly from KNX setpoints.

The grey ABS housing is rated IP54/65. The KNX side is bus powered, while the valve outputs require an auxiliary DC supply. The ETS application is available from the manufacturer on request.

Key Features

  • 4 valve outputs: 0-12 VDC for proportional valves or 24 VDC PWM for thermal actuators
  • Controller modes: PI with PWM or continuous output, continuous input, switching and 2-point
  • Integrated KNX bus coupler (approx. 240 mW from the bus)
  • Auxiliary supply 9-32 VDC, max. 18 W, required
  • Surface mount, grey ABS housing 115 x 65 x 55 mm (4.53 x 2.56 x 2.17 in), IP54/65
  • Operating temperature -5 to +45 °C (23 to 113 °F)
