TCW122B-WD Mô-đun giám sát IP Watchdog

TCW122B-WD được thiết kế để thực hiện giám sát theo cơ chế watchdog (cơ chế theo dõi hệ thống) một cách đáng tin cậy trong các hệ thống mạng và tự động hóa

Features

• Reliable IP watchdog monitoring – Continuous monitoring of network devices using ICMP echo detection.
• Ping-based relay activation – Automatic relay switching when communication is lost.
• Failsafe device restart – Allows recovery of routers, switches and controllers without manual intervention.
• SNMP v.1 support – Integration into existing monitoring systems for status reporting and alerts.
• SNMP trap notifications – Event-based trap messages sent under predefined watchdog or input conditions. 
• Password protected web interface – Secure browser-based configuration and manual control of the device.
• 1-Wire interface for sensors – Connection of up to two temperature or humidity sensors for environmental monitoring.
• Two relay outputs – Relays with normally open and normally closed contacts for flexible control scenarios.
• Analog and digital inputs – Two analog inputs (0–60 VDC) and two digital inputs in dry contact or logic level mode.
• Network security and updates – VLAN and MAC address filtering with support for remote firmware updates.

Applications and use cases

• Watchdog monitoring of networks – Suitable for small and medium-sized network environments.
• ISP and enterprise connectivity – Automatic restart of routers, switches and access equipment. 
• Server room monitoring – Temperature and humidity supervision in technical rooms and data centers.
• Remote control of devices – Switching of electrical equipment using the built-in relays.
