Here we focus on a project involving thirteen analogue input modules and seven analogue output modules for 5V microcontroller’s ADC/DAC channels. In this part, we’ll cover the twelfth and thirteenth analogue input modules, i.e. modules 1 and 2 for a 0-5V or 4-20mA to 0-5V signal converter.

Module 1 handles either DC input voltages from 0V to +12V or DC input currents from 0mA to 48mA, and requires two DC power supplies: +6.26V, +12V. Module 2 handles the same DC input voltages and currents but requires only one power supply, +12V DC.

This article also concludes our study of analogue input modules, and in the next one, we’ll start considering seven analogue output modules.
