System Cooling Accessory Board

Part Number: SCAB

The System Cooling Accessory Board adds the same fan and temperature cooling functions to our USB CFA631 series

  • For cooling, add up to four fans with RPM monitoring and variable PWM fan power control. Connect fans to the SCAB with our 3-pin fan extension cable, WR-FAN-X01.
  • Monitor temperatures with up to 0.5°C absolute accuracy. Add up to 16 WR-DOW-Y17 Dallas Semiconductor 1-Wire (DOW) temperature sensors.
  • 4 GPIO lines on the SCAB allows:
    • ATX power supply control functionality. Use the CFA631 display module keypad buttons as "power" and "reset" buttons for your host system.
    • Hardware watchdog can reset the host in the case of host software failure.
    • Advanced digital GPIO control with PWM output.
  • The SCAB plus CFA631 (which has a built-in bracket) fits nicely in a 1U rack mount case (37 mm overall height).
