IP watchdog monitoring module TCW122B-WD
Watchdog monitoring module designed for reliable ping-based failsafe control
Description
TCW122B-WD is designed for reliable watchdog monitoring in network and automation systems.
The device monitors the presence or absence of ICMP echo (ping) and detects communication loss within a defined time interval.
When a ping failure occurs, the appropriate relay is activated, allowing automatic restart of the monitored device or network equipment.

The unit is intended for installation in server rooms and data centers, where continuous monitoring is required.
Alongside watchdog operation, TCW122B-WD supports monitoring of temperature, humidity, analog voltage and digital inputs.
Collected parameters and device status can be reported via SNMP traps, while the built-in relays allow control of external electrical equipment.

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.
