Monitoring system with 4 relay outputs and 12 signal inputs


Additional information


Expert Net Control 2111 for more security and surveillance in IT infrastructure
  • More security in operation critical IT and AV infrastructure
  • More control through remote access to switchable relay outputs
  • Detect AV and IT problems at an early stage: Proactive power and environment monitoring
  • 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
Key Features
  • Redundant power supply with 2 power connectors and PoE
  • 4 connectors for optional sensors (plug-and-play)
  • Remote switching of 4 relay outputs
  • 12 signal inputs for polling of NO/NC devices
  • Fast and easy installation, also on DIN rail
  • NTP function can be activated
  • Each signal input has 12 V connections to supply NO/NC devices
Switching functions
  • 4 switchable, potential-free relay outputs with changeover connector (NO and NC)
  • High switching capacity 36 V, 3 A
  • Automatic switching of relay outputs depending on sensor thresholds or inputs possible
  • Relays have high contact reliability even with very small loads
  • 4-channel watchdog to monitor connected devices (ICMP/TCP)
  • 4 connectors for combined plug-and-play sensor (temperature, humidity, air pressure) to prevent frequently occurring physical hazards such as overheating
  • 2 power connectors for redundant power supply (12 V DC), as well as Power-over-Ethernet
  • Robust High-Inrush relays ensure safe switching operations
  • Generation of status messages (e-mail, syslog and SNMP traps)
  • Encrypted e-mails (SSL, STARTTLS)
  • Access protection by IP access control
  • Encrypted communication through SSH
  • Secure Login via SSL
  • 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)
  • Easy mounting on DIN rail thanks to mounting clip
  • Easy-to-red LED display for showing IP address, sensor values and error messages
