A watchdog feladata felügyelni egy rendszer működését, tipikusan az ethernet watchdog-nak a hálózati kapcsolatot. Az eszköz low-level szinten működve biztonságosan folyamatosan ping-eli a beállított IP-címet, így ellenőrzi a kapcsolatot, így ha egy bonyolultabb szoftvert üzemelő eszköz (router, modem, switch, stb.) lefagyna, képes újra indítani a hálózati vagy egyéb eszközöket is.
Két relé kimenettel.
TCP szerverként, kliensként, és UDP módon is működőképes, így hálózati kábelen könnyen konfigurálható az eszköz.
Extrém széles hőmérséklet tartományban üzemel, így kültéri kötődobozokba épített hálózati eszközök felügyeletére is alkalmas, ipari környezetben is. ( -40 - +85 °C)
Otthoni vagy kis iroda környezetbe is alkalmas, ha gyakran van router vagy modem probléma az internetten és a folyamatos újraindítással. Biztonságtechnikai környezetben is elengedhetetlen hálózati eszköz, ha a hálózaton kamerák, NAS, adattároló, média eszközök futnak
Szoftver: https://elektrobot.hu/downloads/Tool.exe
Feature:
1. High Temperature Resistance: This controller is high temperature resistant and can work in an environment of -40 degrees to +85 degrees.
2. Normally Closed Output: 2 channel IP relay normally closed output (no normally open output), the output does not carry voltage or current.
3. Featured Function: The relay will actively PING the set IP. When the PING fails, the relay will be disconnected for 10 seconds and then closed (this function is used to restart devices, such as routers).
4. Maximum Load Can be Connected: The controller with chip and program upgrade can be connected to the maximum load, DC 5A, AC 10A, maximum voltage 250V.
5. Application: This is a controller that can be used to monitor whether routers or other devices are disconnected.
Specification:
Item Type: IP Relay Module
Model: HHT-NET2D
Power Supply Voltage: DC5V / DC12V (optional model)
Industrial Grade Working Environment: -40 to +85 Degrees.
The Maximum Load That Can be Connected: DC 5A, AC 10A, Maximum Voltage 250V.

Package List:
1 x Network Watchdog
How to use:
1. The power supply for the 12V version is 7‑24V, 12V is recommended. For the 5V version stable 5V power requiered.
NC1 and COM1 are the first constant closing relay output, and NC2 and COM2 are the second relay output.
2. P5 is used to restore factory equipment. After removing the P5 jumper and powering on again, the factory device can be restored, and the factory device IP is restored to 192.168.0.105. The controller can work in TCP server, TCP client and UDP modes, which is easy to configure using configuration software. After configuration, the jumper wires should be bolted. Turn on the power again.
3. Run the configuration software, select the network card, and click search. After searching the device, double click the list on the left to read the device parameters.
