IP relay control with 4 channels and 8 signal inputs

Expert Net Control 2302-1 for more security and surveillance in IT infrastructure
  • Demonstrably fewer and shorter outages of your critical IT and AV infrastructure
  • More control through remote access to switchable relay outputs
  • Detect AV and IT problems at an early stage: Proactive environmental monitoring and configurable alarms
  • Integrate anywhere: Quickly and easily integrate anywhere with API interface: REST API, https, SNMP, Telnet and MQTT
  • Protection against physical hazards with connected smoke detectors, leakage sensors and door contacts
Massive time and cost savings through plug-and-play drivers from our technology partners
Key Features
  • Remote switching of 4 relay outputs
  • 8 signal inputs allow query of NO/NC devices
  • Connector for plug-and-play sensors
  • Fast and easy mounting on DIN rail
  • NTP function can be activated
  • Special High-Inrush relays prevent sticking of relay contacts during witch on pulse peaks
Switching functions
  • 4 switchable, potential-free relay outputs with changeover connector (NO and NC) and 16 A switching capacity
  • Each power port can be switched via HTTP(S), SNMP, ModbusTCP or command line interface via Telnet, SSH, MQTT and serial interface
  • Switching voltage 230 V AC, 16 A / 24 V DC, 10 A
  • Automatic switching of relay outputs depending on sensor thresholds or inputs possible
  • Simultaneous switching of several switching outputs is prevented by automatic latency of 1 second
  • Relays have high contact reliability even with very small loads
  • States of inputs/outputs are indicated by two-color LEDs on the front panel
  • Self-healing function thanks to 4-channel watchdog: Each power port can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary

  • 1 connector for combined plug-and-play sensors (temperature, humidity and air pressure) to prevent often occurring physical hazards like overheating and increased humidity or air pressure
  • Robust High-Inrush relays ensure safe switching operations
  • Generation of status messages and alarms (e-mail, syslog, SNMP traps MQTT, SSH, Telnet)
  • Encrypted e-mails (SSL, STARTTLS)
  • Access protection by IP access control
  • Encrypted communication through SSL (TLS 1.1, 1.2, 1.3) and SSH
  • Password protected access
  • Easy-to-read LED display for displaying total current, IP address and sensor values
  • Firmware update via Ethernet during operation (no restart required)
  • Simple and flexible configuration via web browser, Windows or Linux program
  • Dynamic assignment of an IP address via DHCP or manual assignment of static IP address
  • Rapid commissioning thanks to free and reliable drivers from our technology partners

The Expert Net Control 2302-1 is a remote I/O system offering various remote control options via a TCP/IP network. The device has four individually switchable potential-free relay outputs and eight passive signal inputs for polling NO/NC devices (e.g. smoke detectors and door contacts). Thanks to the sensor connector (RJ45), the Expert Net Control 2302-1 can be expanded with optional sensors for temperature, humidity, air pressure and leakage monitoring. 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 and enables the surveillance and monitoring of IT installations in no time.
