Ethernet I/O Module
TCW122B-WD is an Ethernet controller, specially designed for IP watchdog monitoring. It controls the functionality of a device or a network by transmitting or receiving respectively ICMP echo request or ICMP echo reply. If there is no ICMP echo (ping) for certain time, the appropriate relay is activated and this can restart the monitored device or network switch. TCW122B-WD has 2 digital and 2 analog inputs, 2 relay outputs and 1-Wire interface and it also can be used for general monitoring and control of environmental monitoring of server rooms. For every of monitored parameters – temperature, humidity, analog voltage and status of digital input, SNMP trap can be sent, if it goes outside of previously set-up range. The relays can be activated remotely (WEB and/or SNMP) or automatically from presence/absence of ping (ICMP echo request or echo replay).
