The TCW112-WD is an advanced IP watchdog relay board designed to monitor the functionality of IP-based devices and networks. It operates by sending ICMP echo requests (pings) to target devices. If a response is not received within a defined time period, the controller automatically activates its relay to power-cycle and reboot the target device.

The board features one digital input, one analog input, and a 1-Wire interface for versatile environmental and parameter monitoring. Its relay includes both normally open (NO) and normally closed (NC) contacts. The relay can be triggered either manually via a WEB interface or SNMP, or automatically when a ping failure is detected.
