IP WatchDog HWg-WR02a monitors the functionality of a device over IP (PING/WEB) or serial line (RS-232), automatically restarts it upon failure. The device can monitor two devices (two independent channels, two 110/230VAC relays). Industrial applications benefit from DIN rail compatibility.
IP WatchDog WR02a (ping restarter) periodically monitors the functionality of a device by transmitting or receiving a specified “I'm alive and OK” signal over IP or RS-232. If the correct reply is not received in time, the device is restarted with a relay. Failures are detected with five distinct methods, separately for each channel (Ping Tx/Rx, Web page request/push, RS-232 data). Web WatchDog WR02a allows flexible configuration – method of functionality detection, switchoff time when restarting.
Applications:
- 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
