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).
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
