SA 230 / 16 / H / EM / KNX REG

Product Information

  • Switching actuator for switching loads
  • DIN-rail mount device, width 72 mm (4TE,  SA4 - 230 / 16 /) or 144 mm (8 TE, SA8 - 230 / 16 /) for mounting on a DIN-rail (TH35 EN 60715) for installation in a switch cabinet
  • Transformer-based current measurement (± 10mA)
  • True effective value measurement (current)
  • Voltage-synchronous active power measurement
  • The device has four (SA4 - 230 / 16 /) or eight (SA8 - 230 / 16 /) independant potential-free NO contacts
  • The switching contacts are optimised for capacitive loads
  • Manual switches for switching without bus tension
  • The switching actuator is powered by the KNX bus, no additional power supply required
  • Connection of the outputs is realised by means of screw terminals
  • The voltage is assumed to be sinusoidal. For the channels 2 ... 4, the phase shift can be adjusted via ETS when using different phase conductors (three-phase alternating current).
