CFA-FBSCAB

The FB System Cooling Accessory Board adds the same fan and temperature cooling functions to our CFA735, CFA835 and CFA635 V1.5.
For cooling, add up to four fans with RPM monitoring and variable PWM fan power control. Connect fans to the CFA-FBSCAB 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 to use with the CFA735 or up to 32 temperature sensors for the CFA835.
For a CFA835, up to 32 CFA-FBSCABs can be connected to each other (“daisy chained”). Maximum configuration will allow 128 fans and 512 temperature sensors.
4 GPIO lines on the CFA-FBSCAB plus CFA835 allows:
- ATX power supply control functionality. Use CFA735, CFA835 and CFA635 V1.5 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 CFA-FBSCAB plus CFA735, CFA835, and CFA635 V1.5 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, CFA-FBSCAB, and a 3.5-inch disk drive. To order a complete Drive Bay Kit, see our Kit Configurator.
