Features:
- Four RJ45 ports connect local industrial Ethernet devices at 10 or 100 Mbit/s.
- LTE, UMTS, and GSM radio paths use two SMA antenna connections for main and diversity reception.
- One isolated input and one isolated relay output operate separately from routed network traffic.
Local Ethernet frames enter Siemens 6GK5876-4AA00-2DA2 through its four-port switch before the routing rules send selected traffic to the cellular interface.
Security processing in 6GK5876-4AA00-2DA2 can translate addresses, filter connection state, or place permitted traffic inside an IPsec or OpenVPN path.
Supply, antenna, field-I/O, and Ethernet wiring on 6GK5876-4AA00-2DA2 remain distinct so each path can be installed and tested independently.
The Siemens 6GK5876-4AA00-2DA2 SCALANCE M876-4 4G Industrial Cellular Router may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

North American Mobile-Radio Path
- Band coverage: The radio section covers documented North American LTE, UMTS, and GSM bands.
- Main antenna: A1 carries the primary mobile-radio antenna connection.
- RX diversity: A2 provides the separate receive-diversity path used by the radio.
- Data boundary: LTE can reach 100 Mbit/s downlink and 50 Mbit/s uplink, while wired ports remain Fast Ethernet.
Routed and Protected IP Flows
- Firewall state: Stateful inspection evaluates packets against configured connection and filtering rules.
- Address translation: NAT, source NAT, and port forwarding control how internal addresses appear externally.
- IPsec path: IPsec can establish protected tunnel or transport connections.
- OpenVPN role: The device can operate as an OpenVPN client for a configured remote service.
Discrete Signal Interfaces
- Input role: The isolated digital input accepts a separate 24 V field-state signal.
- Output role: The isolated relay output switches an external indication or control circuit.
- Output limit: The relay contact is rated for a maximum continuous current of 1 A.
- Path separation: Field signals do not replace the Ethernet ports or the mobile-radio data link.
Supply, Orientation and Temperature
- Supply range: The terminal input accepts 10.8 to 28.8 V DC around the 12 to 24 V rating.
- Vertical position: Vertical mounting with documented side clearance permits operation to 60 C.
- Horizontal position: Horizontal mounting lowers the documented upper operating temperature to 50 C.
- Protection boundary: IP20 requires the router to remain inside a suitable enclosure.
