Advantech ADAM-4012 1-ch Analog Input Module

Advantech ADAM-4012 1-ch Analog Input Module


  • Input type: mV, V or mA


Advantech’s analog input modules use a microprocessor-controlled integrating A/D converter to convert sensor voltage, or current signals into digital data. The digital data is then translated into either engineering units, twos complement hexadecimal format or percentage of full-scale range (FSR) according to the module’s configuration.

When prompted by the host computer, the data is sent through a standard RS-485 interface. The Analog Input Modules offer signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from ground loops and power surges by providing opto-isolation of the A/D input and transformer based isolation up to 3000 V DC.
