RAK5801 WisBlock 4-20mA Interface Module Datasheet
Overview
Description
The RAK5801 WisBlock Interface module was designed to be part of a production-ready IoT solution in a modular way and must be combined with a WisBlock Core and a Base module.
The RAK5801 is a 4-20 mA current loop extension module that allows the users to make an IoT solution for analog sensors with a 4-20 mA interface. This module converts the 4-20 mA current signal into voltage range supported by the WisBlock Core module (MCU) for further digitalization and data transmission.
The RAK5801 module features two input channels of 4-20 mA. Inside, a high-precision operational amplifier is used for signal amplification and conversion and supports a wide range of operating temperatures.
This module integrates a 12 V power supply, which can be used to power external sensors. The RAK5801 can be connected to 2-wire, 3-wire, or 4-wire types of 4-20 mA sensor. The module external interface is reached by a fast crimping terminal that allows connection for the 4-20 mA sensors (including power) and to the I2C bus. The fast crimping terminals can be used without the need of special tools, which simplifies the installation process on the field.
