Moxa (Brea, CA) offers their OnCell G4302-LTE4 LTE cellular router with high-speed performance and reliable communication capabilities between Feeder Terminal Units (FTUs) used to remotely monitor the voltage, current, active power, and reactive power status of high-voltage lines. Because FTUs are often located in unmanaged areas, they can be vulnerable to cyber threats, necessitating the use of secure cellular routers to protect data communication. Additional features include:
- Advanced security functionality based on an IEC 62443-4-2 certified OS, thus supporting cybersecurity for IP-based cellular architecture.
- A firewall can also be set up to only allow logins from recognized IPs, adding powerful protection against DDoS attacks.
- The VPN lets data be encrypted and protected against intrusions.
- A smaller size, dual SIM slots, GbE RJ45 Ethernet ports and an RS-232/422/485 serial port.
- Moxa's GuaranLink 4-tier connection check is embedded in the OnCell G4302 cellular router, offering redundancy to maximize connectivity.
- MXsecurity management software monitors distributed devices and sends alerts in case of link failure.
- MXsecurity keeps managers aware of the statuses of various OT devices and the overall state of network communication.
