WB-MAI2-mini/CC is a compact analog input module designed to measure current signal 4..20 mA via two independent channels. The module is controlled from the controller or PC via RS-485 bus by Modbus commands. | WB-MAI2-mini/CC is a compact analog input module designed to measure current signal 4..20 mA via two independent channels.
