DM20 - DM21 - DM22

IIoT Gateways based on UNIQO

  • ASEM System Manager

Data collection and two-way connection to the cloud

The DM20, DM21, DM22 systems represent a stand-alone solution with book, wall, or DIN rail mounting, dedicated to data monitoring applications, IIoT gateways, and in general applications related to Industry 4.0.


They are based on Linux operating system and ARM Cortex A7/M4 (i.MX7) 1GHz processor with aluminum chassis. They integrate the many advanced features dedicated to Industrial IoT of UNIQO software, including the IIoT Cloud Connector feature that enables the data collection from the field and two-way communication with cloud platforms.


The DM20, DM21, and DM22 systems have two 10/100/1000 Mbps Ethernet ports for Internet and automation device connections, an isolated multi-standard serial interface, and a USB 2.0 port.


The DM21 and DM22 systems can also integrate a Dual-Band Wi-Fi interface and/or a 4G-GLOBAL modem, compatible with international mobile networks. Finally, the DM22 systems include a 4-port Ethernet switch. 


All systems feature an isolated power supply with 9 to 34 VDC input and include two digital inputs and two outputs with freely programmable low-voltage relays via UNIQO.
