TCW122B-WD is an IP watchdog monitoring module, purpose-built for ensuring the reliability of a fail-safe monitoring system.
This module manages the operation of devices or networks through the transmission and reception of ICMP echo requests and replies, respectively. It activates the relevant relay if there is no ICMP echo (ping) response within a specified time frame. This action can serve to reset the monitored device or network switch.
TCW122B-WD is equipped with two digital and two analog inputs. Its two relays feature both normally open and normally closed contacts.
For each monitored parameter, including temperature, humidity, analog voltage, and the status of digital inputs, SNMP traps can be dispatched based on predefined conditions.
The relays can be remotely activated through web-based (WEB) or SNMP control, or automatically triggered by the presence or absence of a ping response.
