Description
The TCW122B-WD is a versatile IP monitoring module built for fail safe operation. It monitors the health of devices and networks by exchanging ICMP echo requests and replies (pings). When a ping fails to occur within a specified period, the module triggers a relay, enabling automated restarts of the monitored equipment.
Beyond its watchdog capabilities, the TCW122B-WD offers two digital and two analog inputs, along with two flexible relays that support both normally open and normally closed connections. It can also generate SNMP traps based on changes in temperature, humidity, analog voltage readings, and digital input states. Furthermore, the relays can be activated remotely through a web interface or SNMP commands, or automatically based on the success or failure of ping checks.
