IEG-3024 Series are mini-size industrial IoT gateway, with 2 10/100Base-TX Ethernet ports, 4 Digital Input & 4 Analog Input ports, wireless (Wi-Fi) connection or 4G LTE miniPCI-e connector type (2 Micro SIM slots) for the wireless application of preference. It helps operating engineers to monitor all factory stages even from wireless devices and predict production failure in advance. IEG-3024 Series permits different protocol devices to coexist at an Ethernet-based interface and data protection is assured with its VPN functions. It supports network address translation (NAT) to enable instances in a private subnet to connect to multiple devices with the same feature function. It supports MQTT protocols to transmit the data from field devices, sensors to the SCADA server through the Ethernet network. This way, PLCs, sensors, factory machines, and wireless devices interact in industrial Ethernet cross-network applications for automation.

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

Communication through Wi-Fi connection 
IEG-3024 supports 2.4 GHz Wi-Fi wireless band connection, and it can operate in AP mode or client mode or AP+client modes. IEG-3024 also supports SMA connectors
to have external antennas connection flexibility.

Secure and Easy-to-use VPN Connection 
Capable of creating a secure VPN (Virtual Private Network), IEG-3010 Series is “VPN client” and can create the VPN tunnel with “VPN server” (Cloud). Using
IEG-3010 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.
