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

What is the ip relay Expert Net Control 2302-1?

The IP relay 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). Sensors send data to the IP relay, it monitors devices and sends the information as a telecontrol system to the user at any time.

Thanks to the sensor connector (RJ45), the Expert Net Control 2302-1 can be expanded with optional sensors to permanently offer rack monitoring. Due to that the climate in a server room can be monitored so that temperature, humidity, air pressure and leakage can be examined immediately. In addition to communication via Telnet, Radius and Modbus TCP, modern security standards such as SNMPv3, SSL and IPv6 are supported to protect the IT infrastructure from unauthorized access.

The Expert Net Control 2302-1 can be easily mounted on a DIN rail, is intuitively usable and monitores IT installations in no time.
