Contemporary Controls' EIGR-C3 VPN router allows for cellular, secure VPN connection to remote sites where a wired connection is not an option. The EIGR Series gigabit IP routers allow one to separate IT and OT infrastructure, with VPN models allowing secure remote access to devices at a job site.
The line has been expanded with the introduction of the EIGR-C3, a 4G LTE cellular router that has been certified and approved for use on Verizon networks. It is a high-speed router that links cellular to 10/100/1000 Mbps Internet Protocol (IPv4) networks — passing appropriate traffic while blocking all other traffic. One network is the local-area-network (LAN); the cellular is the wide-area-network (WAN). It also has an Ethernet port that can act as the WAN if cellular access is not required. The built-in stateful firewall passes communication initiated on the LAN-side while blocking WAN-side initiated communication. With Port Address Translation (PAT), LAN-side clients can access the Internet. The EIGR-C3 incorporates a built-in CAT1 cellular modem, a real-time clock and OpenVPN client functionality compatible with the Cloud-VPN service from Contemporary Controls. The EIGR-C3 operates over a 0 to 60°C temperature range and the EIGR-C3X operates over the −40 to +75°C range.
The router comes with a Verizon SIM pre-installed. Data plan options for 1GB, 3GB and 5GB monthly use are available. Static IP options are also available.
The EIGR-C3 router supports both the main and diversity antennas required for LTE signal reception. A choice of whip antennas that can be mounted directly on the unit or antennas with extension cables can be used. A resident DHCP server on the LAN-side will provide IP addresses to LAN-side clients. Router configuration is via a web browser. The EIGR-C3 comes with DIN-rail mounting, a metal enclosure and the ability to be powered from a low-voltage AC/DC power source.
