Reporting from Shanghai, China
Mar 30, 2021

Reinvent your IoT setup with the ESP32-based controller by SLS, which offers excellent connectivity while measuring power, flow, and temperature data.

Nebulae is an IoT platform which integrates different IoT verticals into one common platform, thus driving interoperability across multi-band networks. Nebulae is created by System Level Solutions (SLS), an IoT firm based in India, which provides a wide variety industrial IoT solutions.

NebuLink NLC1242 is the latest data acquisition system released by SLS. Hosting both Nebulae and Yalgaar frameworks, NLC1242 is designed to serve a wide variety of industrial use cases by bridging the gap between end-user applications and sensors. NLC1242 comes with an ESP32-based dual-core Xtensa 32-bit microprocessor from Espressif Systems. NLC1242 also has an in-built fuse protection circuit which prevents unwanted input fluctuation.


  • ESP32-powered dual-core Xtensa® 32-bit LX6, running at up to 240MHz
  • Power Supply: 16 - 28 VDC at 4A
  • In-built fuse for circuit protection
  • IP65-compliant, wall-mounted enclosure
  • LEDs for status indication
  • Operating Temperature: — 40 °C to + 85 °C
  • Wi-Fi communication interface: 802.11 b/g/n, AP/STA mode
  • Support for cloud connectivity
  • 1 wire interface
  • Analog Input: 2 Channels, 12-bit 0-10V, 4-20mA
  • Digital Input: 4 Channels, 24VDC
  • Digital Relay Output: 2 Channels, 24VDC

The fact that NLC1242 is powered by both Nebulae and Yalgaar SDKs allows end-users to easily integrate the NLC1242 controller into their existing systems, and manage data from the cloud. As such, NLC1242 is ideal for the following applications:

  • Power-generator monitoring and protection
  • Monitoring of air compressors, pumps, etc.
  • Motor protection
  • Fermentation processes
  • Flow and power monitoring
  • Drying ovens
  • Water and waste management
