The Expert Net Control 2302-1 is a remote I/O system that offers various options for remote control over a TCP/IP network. The device features four individually switchable, potential-free relay outputs and eight passive signal inputs for querying NO/NC devices (e.g., smoke detectors and door contacts). Thanks to the sensor connection (RJ45), the remote control system can be expanded with optionally available sensors to monitor ambient temperature, humidity, air pressure, and leakage. In addition to communication via Telnet, Radius, and Modbus TCP, modern security standards such as SNMPv3, SSL, and IPv6 are supported. The Expert Net Control 2302-1 can be easily mounted on a DIN rail, allowing for quick control and monitoring of the IT installation.
