SCAB photo
  • The System Cooling Accessory Board adds the same fan and temperature cooling functions to our CFA631 and CFA635 Intelligent LCD Displays that are available natively (without accessory board) on our CFA533 and CFA633 Intelligent LCD displays.
  • 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 CFA631 or CFA635 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 or CFA635 fit nicely in a 1U rack mount case (37 mm overall height) using our optional mounting bracket. Or buy the SLED chassis that holds the display module, SCAB, and a 3.5-inch disk drive. To order a complete Drive Bay Kit, see our Kit Configurator.
