## Summary description

Rittal 3124.300 is a gateway/controller designed for industrial network integration. It supports Ethernet at 10/100/1000 Mbit/s (IEEE 802.3) and major protocols including OPC-UA, SNMP v1–v3, Modbus/TCP, TCP/IPv4/IPv6, Radius, SSH, Telnet, FTP/SFTP. The device provides a 24 V output, IP20 protection and is intended for connecting and managing devices and telemetry in control cabinets and automation systems.

## Long description

Rittal 3124.300 is a gateway/controller for industrial network integration, designed to connect devices and telemetry inside control cabinets and automation systems. It supports Ethernet at 10/100/1000 Mbit/s and implements common industrial communication protocols such as OPC-UA and Modbus/TCP, along with SNMP v1–v3, TCP/IPv4/IPv6, Radius, SSH, Telnet, FTP/SFTP. The unit provides a 24 V output and has IP20 enclosure protection, suitable for installation in indoor electrical cabinets and rack systems.
Advantages
The Rittal gateway offers multi-protocol support for seamless integration with SCADA, PLCs and higher-level IT systems. Gigabit Ethernet capability ensures high-bandwidth data exchange while protocol flexibility (OPC-UA, Modbus/TCP, SNMP) simplifies connectivity across diverse equipment. The built-in 24 V output allows powering of connected sensors or auxiliary modules directly from the device. Compact design with IP20 protection is targeted at internal cabinet mounting where protection against contact and moderate dust is required.
Suitable for
Aggregating telemetry data from PLCs and field devices into OPC-UA or Modbus/TCP networks
Connecting control cabinet devices to enterprise networks and IT systems
Edge integration for small- to medium-scale automation projects requiring Gigabit Ethernet
When it may not be suitable
The IP20 rating means this gateway is not intended for outdoor use or for environments requiring high ingress protection against water or heavy dust. Applications that demand intrinsic safety, explosion protection or extended environmental sealing will require a different device. Very large-scale installations demanding advanced on-board processing or extensive I/O expansion may need a more feature-rich controller.
Key specifications
Network interface: Ethernet 10/100/1000 Mbit/s (IEEE 802.3)
Supported protocols: OPC-UA, Modbus/TCP, SNMP v1–v3, TCP/IPv4/IPv6, Radius, SSH, Telnet, FTP/SFTP
Supply output: 24 V DC output for powering peripheral devices
Enclosure protection: IP20 (suitable for internal cabinet mounting)
Colour and mounting: black housing designed for cabinet or rack installation
How to use
Install the gateway inside a control cabinet on a DIN rail or suitable mounting plate according to cabinet layout and clearance requirements. Connect the Ethernet network using compatible Cat5e/6 cables to the device ports and configure IP settings for TCP/IPv4 or IPv6 as required. Enable and configure required communication stacks such as OPC-UA or Modbus/TCP through the device management interface, and set up user authentication via Radius or SSH where needed. Use the 24 V output to feed sensors or auxiliary modules, observing current limits and wiring polarity. Validate communication with connected PLCs and monitoring systems before commissioning.
What to consider before purchase
Environment: IP20 is for internal cabinet use only; choose higher IP rating for outdoor or harsh environments
Protocol compatibility: confirm that OPC-UA, Modbus/TCP or other supported protocols match your existing devices and SCADA/IT systems
Power and wiring: ensure the 24 V output power and available current meet the needs of connected peripherals
Network infrastructure: verify that your network switches and cabling support Gigabit Ethernet if required
Usage recommendations
For reliable operation, mount the gateway in a temperature-controlled cabinet, use shielded Ethernet cabling where noise is present, and secure management access with strong authentication (Radius/SSH). Test protocol configurations in a staging environment before full deployment and monitor device health using SNMP or integrated logs.
