JB 521C23 - Shutter Blind Actuator, 2 x AC 120 V, 6 A

Shutter Blind Actuator, 2 x AC 120 V, 6 A

• The solar protection actuator is a KNX device with two relay
  output channels.
• The device is installed in 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.
  
• The device may be used to control blinds, shutters, awnings, windows, or doors.
  
• The device is designed to drive (per channel) one AC 120V drive (motor) with electromechanical limit switches or with integrated electronics for disconnection at the limit positions.
  
• For drives with electromechanical limit switches the actuator can be configured to detect the status of the electromechanical limit switches such that the travel time between the end positions can be measured via a synchronization
  run.
• The travel time of the blind / shutter is automatically measured from the upper end position to the lower end position and vice versa.
• The measurement is only reliable for drives with electromechanical limit switches.
