JB 526C23 - Switch/dim actuator, 2 x AC 277 V, 20 A, 1...10 V

Switch/dim actuator, 2 x AC 277 V, 20 A, 1...10 V

• The device is a KNX device for controlling up to two groups (channels) of lamps via the DC 0/1-10 V control terminal of dimmable led drivers (ECGs).
• In addition, there is per channel a switching contact for direct switching on/off of the connected lamps.
  
• The device is installed into or attached to a 4 x 4 inch junction box. The bus is connected via a bus terminal block.
• The actuator electronics are supplied via the bus voltage.
  
• Each channel can control several dimmable electronic ballasts.
• Their number is limited by the switching capacity and by the control power.
• If the on/off function is not used via the switching contact, the number of controllable ECGs is only dependent on the load of the DC 0/1-10 V control voltage.
• This might allow controlling a larger number of drivers (see Technical Specifications below).
  
• Various functions can be configured per channel such as for switching on/off lamps, dimming up / down or setting a particular dimming level.
  
• Amongst others, the application program includes an optional counter for switching cycles and operating hours with threshold monitoring for each output and an integrated 8-bit scene  control for incorporating the output into
  up to 8 scenes.
