COMMUTATOR FOR PROVIDING AUTONOMOUS OPERATION OF INSTRUMENTATION AND/OR AUTOMATION CONTROLLERS VIA INTERFACES: 4-20 mA/HART, AND/OR RS-485, AND/OR RS-232 (MODBUS PROTOCOL), AND WIRELESS DATA TRANSMISSION IN LoRaWAN NETWORKS, AND/OR NB-IoT AND/OR 6LoWPAN Russian patent published in 2022 - IPC G01R19/00 

FIELD: transmission technology.

SUBSTANCE: invention relates to signal transmission technology, in particular to switches for the operation of instrumentation. The effect is achieved by the fact that the switch contains a HART modem and an RS-485 driver that allows data exchange with devices operating via the HART protocol and RS-485 interface, the HART modem output is connected to the controller input/output and the matching filter input, the input of which is connected via shunt and EMI filter (EMF) to the HART output of the device, the output of the shunt is connected through the second FEP and through the matching unit to the controller, and the device with the output interface 4-20 mA, HART protocol (RS-485 interface) is powered by a voltage converter that sets the current and voltage for powering the connected devices from the battery which are connected to the controller, and the RS-485 driver is connected to the input/output of the controller and through the third FEP to the data acquisition device, while the controller is connected to the LoRaWAN communication module (NB-IoT and/or 6LoWPAN) for data transmission over a wireless network and to the memory module.

EFFECT: expansion of the functionality of the device.
