Description

My first trying to make STM32-based PLC like BARTH STG-800

**Main goals:

  • Medium-density performance 32 Bit ARM® Cortex® STM32F103C8T6
  • 5 Inputs: 3 analog Inputs 0-30 VDC (12 bit ADC) or Digital inputs + 2 Digital inputs (software defined)
  • 5 Solid-State Power Outputs up to 18A each
  • Basic Fail Safe Functions
  • Programmable Status LED
  • TTL-232 3.3V Interface
  • Open Source Programming
  • Wide Operating Voltage Range 7 to 30 VDC
  • Wide Operating Temp. Range -40 to +70°C

2 layer board top layer is GND, bottom layer is 30V source. Power source and inputs have simple resistor voltage dividers. Outputs based on highside solidstate swithes.
