This series of columns is dedicated to a project involving thirteen analogue input modules and seven analogue output modules for a 5V microcontroller, connecting them to its ADC and DAC channels.

This month we will cover the fifth and sixth analogue output modules, i.e. the 0-5V to –10V – +10V signal converter’s analogue output modules 1 and 2. Module 1, and then module 2 respectively provide voltages from –10V to +10V, requiring three DC power supplies (+5V, –12V, +12V) for module 1, and two (–12V, +12V) for module 2.
