WB-MAI2-mini/CC 4-20mA Modbus Analog Inputs/en: различия между версиями

The web interface for the module displays current values (controls "Current input 1 (mA)" and "Current input 2 (mA)"), supply voltage and serial number. The "CC" in the device name indicates that it supports two current inputs ('''C'''urrent).

== Description of Modbus registers ==

All Modbus registers of the device are divided into 2 groups:

* General registers that define device parameters

* Registers of measured values
