LTE 4G Cellular Gateway with PLC extension

The maxx GW 4102 with PLC extension is a robust industrial IoT Gateway. This Linux-based, freely programmable Industrial Gateway for profile rail mounting communicates via the high-availability LTE cellular radio standard and thus guarantees you the highest connection security. Thanks to the “Always-Online” functionality, the Gateway establishes a connection independently and, in the event of an error, automatically re-establishes the connection. Thus, you have unrestricted access to the maintenance-free device at any time and from any location.

The maxx GW4102 LTE 4G Cellular Gateway offers many benefits

Based on the maxx GW4100 LTE 4G Cellular Gateway, the variety of interfaces and connections for the maxx GW4102 was supplemented by communication with external programmable logic controllers (PLC/SPS). This results in additional application options:

  • Digital outputs from controls may be connected directly.
  • The cabling of the 16 digital, isolated inputs is significantly simplified by the cascading of the inputs and outputs and the assignment of the connectors.
  • Four digital, isolated outputs with up to 300 mA switching current are possible.
  • Counter inputs for frequencies up to 1 kHz can be implemented with the digital inputs from the Linux user space.

Exceptional Capacity

The LTE 4G Industrial Gateway has a slim, expandable Linux operating system and a current processor system.  
The system is generously equipped with flash and RAM memory and also allows the use of SD cards for very large or frequently changed data.

Encrypted Access

Thanks to OpenVPN, your device management takes place via encrypted dial-in via cellular communications. This means that our devices may only be accessed by the users themselves. Security updates and bugfixes for the Linux operating system as well as for your individual applications and configurations are carried out via our centralised “Over-the-air” firmware update service. This ensures a reliable remote update procedure.

Various interfaces & PLC extension

The programmable Sensor Gateway processes applications in different programming languages. You can either use predefined functions or, if you prefer, individually customised functions. In addition, the device also incorporates your own applications.  
The Industrial IoT Gateway provides various physical interfaces for connecting end devices with communication interfaces and / or sensors, e.g. Ethernet, USB, RS-232, RS-485, CAN bus and 1-Wire.
The PLC extension provides additional, isolated, digital inputs and outputs that enable the simple connection of digital output and input signals. These may e.g. come from programmable logic controls and create additional communication options

High Level of Security

The maxx GW 4102 Cellular Gateway provides your data with extra security and protection against manipulation using VPN technology, the integrated firewall and the optional security chip, which ensures extremely well-encrypted data communication.
