Monitoring system with 8 relay outputs and 8 signal inputs


Additional information


Expert Net Control 2304-1 for increased operational reliability and energy efficiency in DIN rail installations
  • Demonstrably more security in your critical IT and AV infrastructure
  • More control through remote access to individually switchable relay outputs
  • Detect AV and IT problems early: Proactive environmental monitoring through plug-and-play sensors
  • Integrate anywhere: Quickly and easily integrate anywhere with open API: REST API, HTTPS, SNMP, Telnet, and MQTT
  • Defend against physical hazards with connected smoke detectors, leakage sensors and door contacts
Key Features
  • Event and schedule controlled switching
  • Signal inputs for polling NO/NC devices (e.g. door contact, smoke detector etc.)
  • 1 connector for plug-and-play sensors for real-time monitoring
  • Easy and fast mounting on mounting rails with top hat profile
  • NTP function can be activated
  • More flexibility through Radius, Modbus TCP and MQTT 3.1.1 support
Switching function
  • Each power port can be switched via HTTP/S, Telnet, SSH, SNMP or command line interface
  • Programmable on/off sequences for remote reboots (Remote Reboot)
  • Power ports can be switched when preset sensor thresholds are exceeded
  • Self-healing function thanks to 8-channel watchdog: The power ports can be assigned its own Watchdog (ICMP/TCP), which initiates an automatic restart if necessary
  • Switching state and switch-on delay up to 9999 seconds (166 minutes) individually adjustable for each output port after power failure
  • Current peaks due to increased inrush currents are automatically prevented by sequential switch-on with a latency of 1 second
  • Generation of status messages via e-mail, syslog, SNMP traps, Telnet, SSH and MQTT depending on set thresholds of the sensor measurement
  • Encrypted e-mails (SSL, STARTTLS)
  • Access protection by IP access control
  • Encrypted communication through SSH
  • Secure Login via SSL
  • Beeper for audible alarm when sensor limits are exceeded/deceeded
Metering function
  • Connection for combined plug-&-play sensors (temperature, humidity and air pressure) to prevent frequently occurring physical hazards such as overheating and increased humidity or air pressure
  • Easy-to-read LED display for displaying total current, IP address , sensor values and error messages
  • 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
  • Convenient control on the go via free GUDE Control+ app (Android and iOS)
  • Rapid commissioning thanks to free and reliable drivers from our technology partners
Electrical Connections
  • 1 Mains connection with 230 V AC or 30 V DC (terminal clamps)
  • 8 switching outputs (terminal clamps)
  • 8 passive signal inputs (terminal clamps)
  • 1 Ethernet connector RJ45 (10/100 Mbit/s)
  • 1 connector (RJ45) for plug-&-play sensors
