Güde Expert Net Control 2111-1 Power Monitoring Unit, DIN Rail, 16A, Ethernet

Network power monitoring unit for precise energy measurement on DIN rail. The Güde Expert Net Control 2111-1 monitors voltage, current, active power, reactive power, apparent power, frequency, power factor, and energy consumption for single-phase circuits up to 16 A. With its integrated web interface and support for SNMP, Modbus/TCP, and MQTT, it integrates seamlessly into existing network management systems.

Advantages

Accurate measurement (±1%) of all key electrical parameters enables detailed energy analysis and proactive capacity planning. The device features two digital inputs and two relay outputs for alarm integration and remote control. Data logging with timestamp storage allows long-term trend analysis. Secure access via SSL/TLS, SSH, and user management protects your infrastructure.
