TCW122B-WD is an IP Watchdog monitoring module, based on the TCW122 hardware. It has two digital and 2 analogue inputs, plus 1-wire sensor support for temperature and humidity sensor. Two relay outputs for remotely switching devices (offering both normally open and normally closed wiring options). The controller supports SNMP v1 as M2M protocol. It can also be used as a part of a small to medium SCADA systems for environmental monitoring of server rooms.
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, analogue 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.
