Use cases

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
  • 8 switchable, potential-free relay outputs with 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
  • 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: Each power port 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

Metering function
  • 1 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
Security
  • 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
  • Beeper for audible alarm when sensor limits are exceeded/deceeded
Operation
  • 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

IP relay Expert Net Control 2304-1 – smart control and monitoring via network

The Expert Net Control 2304-1 is a network-compatible power switch in a DIN rail enclosure with 8 relay outputs and 8 signal inputs. It enables the flexible control and monitoring of connected devices via remote access. Thanks to the signal inputs, NO/NC devices such as smoke detectors or door contacts can be integrated – ideal for AV installations, IT systems and data centres.

Smart monitoring solution for maximum operational reliability

The relay outputs can be switched via a web interface, SNMP, MQTT or directly on the device using a button. Support for SNMPv3, SSL, IPv6, Telnet, Radius & Modbus TCP enables seamless integration into existing networks.

The integrated Remote Monitoring System (RMS) sends automated messages as soon as sensor readings or signal inputs exceed critical limits. This enables early maintenance measures to be taken before system-critical conditions occur.
