IP WatchDog HWg-WR02a: ping restarter

IP WatchDog HWg-WR02a monitors two devices over IP (PING/WEB) or serial line (RS-232), automatically restarts any of them if it stops responding – autonomous ping relay restarter.

IP WatchDog WR02a periodically monitors the functionality of a device by transmitting or receiving a d

efined  “I'm alive and OK” signal. This signal can be received over IP (PING or WEB) or RS-232 (serial port). If the correct reply is not received in time, the controlled device is restarted using a relay.

Industrial applications can benefit from DIN rail mount and internal relays that can directly switch 110/230VAC, max 16A. Failure

s are detected with five distinct methods, separately for each channel (Ping Tx/Rx, Web page Tx/Rx, RS-232 Rx data).


  • Operation monitoring / IP restart: servers / routers; IP video cameras; WiFi links / access points; industrial systems 
  • Connectivity monitoring: activation of a back-up link; detection of connectivity outage (relay >> horn); monitoring of ADSL and cable modems; security and access control systems
