System Monitoring/Fan Regulation

Features at a Glance:

  • The system monitoring module provides for the activation of fans and for the monitoring of supply voltages
  • The module supports the monitoring of up to 4 voltages (+3.3V, +5V, +12V, and -12V)
  • A minimum and maximum value can be defined for each of these voltages
  • Unit is designed for 12V fans with tacho signal
  • Up to 8 fans are supported
  • Fans are divided into 4 groups of 2 fans
  • One of 4 temperature sensors (X11-X14) can be assigned to each group
  • The maximum current  is 1.5A per fan
  • The supply voltage is 12V
  • NTC temperature sensors with 33kOhm and 100kOhm are supported
  • All current values are cyclically output on a 2-line LCD display on the module
  • The LCD contrast can be adjusted through the potentiometer R66
