Contemporary Controls EIGR-E : Skorpion Gigabit Wired IP Router, 10/100/1000 Mbps WAN + 4-Port LAN Switch, Stateful Firewall + NAT/PAT/Port Forwarding, Allowlist, UL 508 Industrial Control Equipment, 41mm DIN-Rail, 10-36VDC/24VAC Redundant Power

The EIGR family is Contemporary Controls' gigabit Skorpion router line, all sharing the same 41 mm DIN-rail enclosure, 4-port gigabit LAN switch, stateful firewall, and NAT/PAT/Port Forwarding capabilities. The differences come down to temperature range and VPN capability: EIGR-E (0 to 60°C, no VPN), EIGR-EX (-40 to +75°C, no VPN), EIGR-V (0 to 60°C, OpenVPN client/server with 15 router + 15 PC clients), EIGR-VX (-40 to +75°C, same VPN as EIGR-V), and EIGR-VB (0 to 60°C, OpenVPN client + bridge-mode server with 10 PC clients and broadcast/multicast pass-through). Pick by environment first, then by VPN need.

The EIGR-E is rated 0°C to +60°C (+32°F to +140°F), suitable for conditioned indoor panels and most mechanical rooms. For outdoor installations, rooftop enclosures, unconditioned warehouses, refrigerated environments, or any panel where ambient temperature can exceed 60°C in summer or drop below 0°C in winter, choose the wide-temperature variant: EIGR-EX (wired, no VPN) or EIGR-VX (wired with OpenVPN client/server). Both are rated -40°C to +75°C with otherwise identical features to their standard-temp counterparts.

Yes. The EIGR-E is UL 508 Listed for Industrial Control Equipment and CSA C22.2 No. 142-M1987 compliant. UL 508-listed components are directly acceptable for use in UL 508A panels without invalidating the panel listing, as long as the device is supplied from a Class 2 limited-energy source per the panel's circuit requirements.

Yes. The EIGR-E accepts 24 VAC ±10% on a half-wave rectified low-voltage input, which lets it share a common 24VAC source with other control devices such as actuators, valves, and thermostats. A second power input accepts 10-36 VDC for either redundant power or DC-only installations. The two inputs are independent - you can mix sources (for example 24 VAC primary with a 24 VDC battery backup). Power consumption is 7 W DC or 11 VA AC.

No. Like most IP routers, the EIGR-E does not forward broadcast messages between subnets, which BACnet/IP relies on for device discovery and Who-Is/I-Am traffic. The standard solutions are to deploy a BACnet/IP Broadcast Management Device (BBMD) on each subnet, or to enable Foreign Device Registration (FDR) on remote BACnet devices so they can register with a single central BBMD. Contemporary Controls' BAS Router (BASRT-B) is commonly paired with the EIGR-E to provide BBMD functionality alongside MS/TP-to-IP routing. For BACnet broadcast traffic across a VPN specifically, see the EIGR-VB which uses bridge-mode VPN to pass broadcasts through the VPN tunnel.

For typical BAS panels running BACnet/IP between controllers, 100 Mbps is more than sufficient and the older EIPR series remains a cost-effective choice. Gigabit becomes worthwhile when at least one device on the network natively prefers gigabit - IP cameras and NVRs, Niagara Supervisor stations and historian-heavy JACEs, BACnet/IP networks with thousands of points polling at high frequency, large building portfolios where the panel network is part of a corporate gigabit infrastructure, or applications doing bulk data transfers (firmware updates, log retrievals). The EIGR-E also future-proofs your panel network: deploy gigabit today, run at 100 Mbps if that's all your devices need, and gain headroom for additions over the panel's 15-20 year service life.

The default LAN-side IP address is 192.168.92.1 with subnet mask 255.255.255.0. To configure, connect a PC directly to one of the LAN ports with the PC set to obtain an IP address automatically (the EIGR-E's built-in DHCP server will assign the PC an address), then browse to http://192.168.92.1. Default username and password are both admin and must be changed on first login (8-63 characters, at least one letter and one number required). The reset switch on the front panel restores factory defaults if you need to start over - hold for at least 3 seconds while powered, then power-cycle the unit.
