WebFan Tachometer Open Collector Circuit. An open collector design, typically used for CPU fan tach signals, is a very simple digital way to transfer rpm information. As you can see … WebNov 19, 2024 · Certain fans have either a tachometer output wire that reads speed or an alarm if the fan stops. The EBB 36 has multiple I/O pins that could likely be repurposed to be inputs for that purpose but if the fan comes with 3-wire connections they will have to be re-wired. Morph Member Nov 19, 2024 #6
