Description
The 4..20mA to NB-IOT converter allows the transmission of any analog signal respecting the 4..20 mA current loop standard. This converter makes it possible to connect any sensor or actuator, through a pair of electrical conductors in which circulates a current whose intensity is proportional to the signal to be transmitted.
The 4-20 mA current loop is the most widely used principle in the industry because it allows linear representation of the signal to be measured. The intensity of the current is directly proportional to the intensity of the signal to be transmitted. The benefits are many. On the one hand, the current loop has the advantage, compared to the voltage loop, of not being affected by line losses. So we get better accuracy.
This NBIOT converter also has an analog input, 2 digital inputs and a hall sensor.
A PC configuration program, connected to the NB-IOT Transmitter, via a micro-USB port, allows the configuration of security/digital inputs and 4-20 mA interface. Data collection and data transmission frequencies may be specified as 2 independent parameters. Data are transferred through MQTT.
