IEG-3024-L is an Industrial Gateway that connects various interface and generation devices to an Ethernet network for a reduced CaPex and low OPEX. The 2-port 10/100 RJ45 uplink connects to the control center or to other gateways to make ring connectivity. Using Modbus RTU to TCP, the most common Ethernet communication packets, sensors can have back and forth communication with the device through its digital and analog ports.

Designed with MQTT protocols the device delivers encrypted packets between client and server through 4G LTE bandwidth at long distances. The device offers a dual sim-card redundancy system to keep the LTE communication always active.

This Gateway is built with industrial-grade components and enclosed in an IP30 case with high thermal conductivity, which protects the device from tools and hazards. Designed to withstand vibration, shock, free fall, interference, and temperatures ranging from -40℃~75℃ (-40°F~167°F), it suits extreme industrial environments. To ensure reliability the redundant power supply and alarm relay contact on the terminal block ensures non-stop operations and issues alerts if power fails. The reset button restores the device to default factory settings if an issue arises after configuration. To ensure reliability the redundant power supply and alarm relay contact on the terminal block ensures non-stop operations and issues alerts if power fails.


MQTT messaging protocol support 
Supporting MQTT (Message Queuing Telemetry Transport) for data exchange between clients and the server. 

Secure and Easy-to-use VPN Connection
Capable of creating a secure VPN (Virtual Private Network), IEG-3024 Series is “VPN client” and can create the VPN tunnel with “VPN server” (Cloud). Using IEG-3024 series, you can instantly access your office resources through a secure VPN connection.

Digital Input and Analog Input 
It has 4 DI and 4 AI input ports to receive analog inputs and digital inputs. The analog input type (Voltage or Current) can be selected using DIP switch.
