Industrial IP30 LoRa Node Controller (2 DI, 2 DO, EU868/US915 Sub 1G)

» LN1140

Build a Smarter, Connected World

PLANET LN1140 is an Industrial LoRa Node Controller used for data acquisition from multiple sensors. It contains two digital input interfaces and two digital output interfaces to simplify the deployment and replacement of LoRaWAN networks. It can be used to monitor and control embedded devices such as temperature sensors, access control systems, security systems, and more. With its industrial design and IP30 metal case, the LN1140 is widely used in indoor applications like smart industries, building automation, etc.

 

LoRaWAN-based Controller with Rich Industrial Interfaces

The LN1140 LoRaWAN Controller with built-in two DI interfaces and two DO interfaces connects to all types of devices with DO and DI interfaces. The LN1140 supports LoRaWAN class C protocol to be in full compatibility with standard LoRaWAN gateways including PLANET LCG-300 series. It is ideal for large-scale IoT application deployments, such as projects for building automation, smart metering, HVAC system, etc. With multiple interfaces, LoRaWAN Controller can perfectly help retrofit legacy assets into IoT enablement.

LoRa and LoRaWAN Wireless Technology

LoRa or long range is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread spectrum (CSS) technology. LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). LoRaWAN defines the communication protocol and system architecture. The LN1140, supporting Modbus protocol and serial communication, is ideal for LoRa-enabled devices in the IoT system.

 

Multiple LoRa Frequency Bands

The LN1140 supports the following license-free sub-gigahertz radio frequency bands:

  • EU868 (863–870 MHz) in Europe
  • AU915/AS923-1 (915–928 MHz) in South America
  • US915 (902 to 928 MHz) in North America
  • IN865 (865 to 867 MHz) in India
  • AS923 (915 to 928 MHz) in Asia
  • KR920 (920 to 923 MHz) in South Korea
  • RU864 (864 to 870 MHz)

 

Easy Installation in Limited Space

The compact-sized LN1140 is specially designed to be installed in a narrow environment, such as wall enclosure. It can be installed by fixed wall mounting or DIN rail, thereby making its usability more flexible and easier in any space-limited location.

 

 

Environmentally Hardened Design

With the IP30 metal industrial case, the LN1140 provides a high level of immunity against electromagnetic interference and heavy electrical surges which are usually found on plant floors or in curb-side traffic control cabinets without air conditioning. It features a ventilated construction in which a cooling fan is not necessary, thereby making its operation noiseless. Being able to operate under the temperature range from -40 to 75 degrees C, the LN1140 can be placed in almost any difficult environment.

LoRa Communication Solution

The LN1140 is a versatile device that supports both LoRa and LoRaWAN standards, which is ideal for monitoring and controlling embedded devices such as temperature sensors, access control systems, and security systems. It offers various functions, including controlling node settings and configurations, data transmission, data collection and analysis, and managing the LoRa network, node management, and other related functions.

 

Overall, the LN1140 is a reliable and efficient solution for managing LoRa networks and controlling embedded devices, making it an essential tool for businesses and organizations looking to streamline their IoT operations.
