RF Rx SW915-4S 24VDC Power-down-function

Wireless receiver
Material number: 1393796
  • sWave® wireless technology
  • 4 potential-free relay outputs
  • 4 NO contacts, max. 3 A
  • Transmitter/receiver assignment by teaching mode
  • LEDs for indication of switching state
  • SMA reverse plug-in connector for external antenna
  • Power-down-function (saves the last signal status from the relay output, if the power supply of the receiver box is interrupted)
  • External antenna always required for optimum wireless range
