RF Rx EN868-2W-s-RS232

  • EnOcean® wireless technology
  • 2 potential-free relay outputs
  • 2 change-over contacts, max. 6 A
  • RS 232 interface
  • Version with Power-down function
  • Transmitter/receiver assignment by teaching mode
  • LEDs for indication of switching state
  • SMA plug-in connector for external antenna
  • The current switching status of the device is stored when the power supply is turned off. When the supply voltage returns, the last switching status is restored. When the device is voltage-free, any switching operations are lost. A maximum of 100,000 memory operations are possible.
