Editorial narrative

Product Description RAK5801 is a WisBlock Interface that extends the WisBlock system with two current measurement inputs. The current is converted into a voltage that can be read by the analog input pins of the WisBlock Core module. A ready-to-use SW library and tutorial make it easy to connect any sensor that is using a 4-20mA current output. RAK5801 supports two 4-20mA interfaces and has a 12V power output to supply sensors. In addition, an I2C interface connection is available on the crimping terminal. RAK5801 combined with the RAK4631 WisBlock Core gives your solution an interface to industrial sensors and actuators that supports the 4-20mA interface. This module is the bridge between such sensors and LoRaWan® communication, LoRa® point to point connections, or BLE. RAK5801 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows to power down the module completely to reduce the power consumption of the system even more. Key Features 4 to 20mA current to voltage converter. Low power consumption Small form factor 12V output for sensors 0.005mA conversion accuracy 2kV ESD protection Supports 2 RS485 Ports Package Inclusion 1pc RAK5801 Documentation RAK5801 Datasheet
