The PLANET LN1140 is an industrial-grade LoRa Node Controller designed for intelligent IoT applications. Featuring two digital input and two digital output interfaces, it enables seamless integration of various embedded systems such as temperature sensors, access control units, and security devices. Supporting LoRaWAN Class C and compatible with PLANET LCG-300 series gateways, the LN1140 is ideal for large-scale deployments including building automation, smart metering, and HVAC systems.

The device operates on multiple international LoRa frequency bands and comes in a compact, IP30-rated metal enclosure, suitable for space-limited industrial environments. Its fanless design ensures quiet operation, while its wide input voltage range (9–48V DC or 24V AC) enhances flexibility. With built-in status LEDs and a temperature sensor, the LN1140 provides real-time diagnostics and reliable performance.
