The TCW122B-WD is a professional-grade IP watchdog monitoring module engineered to ensure maximum uptime for critical network infrastructure. By utilizing ICMP echo (ping) monitoring, the module continuously tracks the connectivity of networked devices. If a target fails to respond within a user-defined timeframe, the module automatically triggers its relays to power-cycle and reboot the unresponsive equipment or network switch.

Equipped with two digital and two analog inputs, the TCW122B-WD offers comprehensive environmental and electrical oversight. It supports SNMP traps for proactive alerts on critical parameters, including temperature, humidity, analog voltage, and digital input status. Relays can be controlled seamlessly via a dedicated WEB interface, SNMP commands, or through automated watchdog logic, providing a robust solution for remote site management and automated fault recovery.
