Empowering industrial IoT connectivity


DP-SELTA STCE-SG IoT & LoRa module serves as an Industrial IoT Gateway, linking End Nodes – representing smart edge devices and sensors spread across a wide area – with a central network or cloud platform for storage, analysis, and visualization. Its high sensitivity allows the module to receive weak signals from distant devices even in challenging environments. As a Gateway, the module converts legacy serial protocols to modern IP-based protocols, enabling seamless communication from the IP SCADA to both the old and new RTUs.

Functioning beyond its gateway role, STCE-SG IoT & LoRa module extends its capability as a Long Range (LR) transmitter and facilitates the gathering, receiving, and secure transmission of encrypted data from widely dispersed End Nodes to LoRa gateways ensuring the confidentiality and integrity of the data which are a critical facet in the industrial landscape.

With integrated Network and Application servers, STCE-SG IoT & LoRa module offers powerful Data Aggregation and Edge IoT Computing* by hosting 3rd party container software for customized applications capabilities for localized storage and processing of consolidated data from multiple End Nodes. This integration helps to reduce latency and minimize the amount of data transmitted to the cloud.

Built to address the requirements of the Low Power Wide Area Network (LPWAN), STCE-SG IoT & LoRa module enables efficient long-range communication, energy-efficient data collection & processing, and cost-effective management for a variety of industrial applications to become an ideal solution for rural and other non-dense areas saving CAPEX and OPEX.

STCE-SG IoT & LoRa module features DIN-rail mounting, a wide operating temperature range (-25°C ÷ +65°C) without active fan support, and safe data processing operations at humidity levels between 5÷95 %.
