For Ax channels, the input stage consists of an ADCx analog-to-digital converter and Rx input impedance (100 kΩ). The ADCx converter has a high input impedance, it is connected continuously and does not affect the channel operation in output mode. In the input mode, the Tx key is deactivated (open) and therefore does not affect the voltage measurement at the channel terminal. The input impedance of the channel is determined by the Rx resistor in input mode: if no other circuits are connected to the channel terminal, the resistor will "pull" the input voltage to "0 power", and the ADCx converter will assume the voltage to be 0. The analog inputs on the channels are displayed in Ax as an Ax section of the ADC. The channel path is: "wb-adc/Ax". | For Ax channels, the input stage consists of an ADCx analog-to-digital converter and Rx input impedance (100 kΩ).

There is a function of binary input DI for Ax channels - the controller perceives the terminal voltage more than 3 V as a logical unit (input operation), and less than 1.5 V — as a logical zero. The binary inputs on the Ax channel are displayed as Ax_IN in software. The address of the binary input channel is "wb-gpio/Ax_IN". | |||
