Güde 2302-1 Remote Power Controller Black

Expert Net Control 2302-1 (Güde 2302-1 Black) is a networked I/O controller for remote power and sensor management over TCP/IP. The compact device provides four individually switchable potential-free relay outputs and eight passive signal inputs for monitoring normally-open (NO) and normally-closed (NC) contacts, such as door contacts or smoke detectors. An RJ45 sensor interface allows connection of optional sensors for ambient temperature, humidity, air pressure and liquid leak detection. Communication supports Telnet, RADIUS and Modbus TCP, and security features include SNMPv3, SSL and IPv6 support.

Advantages

The unit offers flexible remote control and monitoring via standard network protocols, multiple relay outputs for independent switching and a variety of sensor expansion options through the RJ45 interface. Security and compatibility are enhanced by support for SNMPv3, SSL and IPv6, while the compact German-made design provides straightforward integration into Windows and Linux environments.

Suitable for (tasks / use cases)

• Remote switching of equipment and power lines using potential-free relays
• Monitoring door contacts, smoke detectors and other NO/NC sensors
• Environmental monitoring with temperature, humidity, air pressure and leak sensors
• Integration into network management systems via Telnet, Modbus TCP or SNMPv3

How to use

Install the unit in a suitable network location and connect the relay outputs and signal inputs to the devices you wish to control or monitor. Attach optional sensors to the RJ45 sensor interface when environmental monitoring is required. Configure network settings and user access via the built-in TCP/IP interfaces, then control relays and read inputs over Telnet, Modbus TCP or through SNMPv3-compatible management tools. Ensure the device is connected to a system running supported operating systems (Windows or Linux) for any required local configuration utilities.

Recommendations

For reliable operation, place the controller in a dry, ventilated area and use shielded cables for sensor and input wiring where electromagnetic interference is possible. Secure network access with SSL and SNMPv3 and verify sensor compatibility before installation.
