SmartFan TachScan-3 Fan Speed AlarmOperation/Installation Manual

SmartFan TachScan-3 fan speed alarm monitors tach pulses from up to three DC or AC fans or blowers and provides OR’d pass/fail signals. TachScan-3 is compatible with any fan that provides open collector or voltage source tach pulses. Three fan speed alarm trigger speeds are selectable by jumper.
If the speed of any air mover falls below the trigger speed, alarm signals are generated. Fan speed alarm signals can drive LEDs, logic, optical isolators or MOS Relays.
In addition to the standard line of SmartFan controls and alarms, Control Resources also provides custom control design and manufacturing services to provide you with the optimum cooling solution for your OEM fan speed alarm applications.

Product Features – SmartFan TachScan-3 Fan Speed Alarm

    • P/Ns 030M320-F and 030M320R-F accept any supply voltage from 6 to 60
      VDC and distribute power to DC fans through the same header used to
      sense tach pulses.
    • P/Ns 030M3205-F and 030M320R4-F accept any supply voltage for 6 to 60
      VDC and power the DC tach circuits built into AC fans.
    • Three inputs monitor fans with any open collector or voltage source
      tach pulses.
    • P/Ns 030M320-F and 030M3205-F provide simultaneous NO and NC open
      collector outputs from optical isolators which can sink up to 1.0 mA
      to drive logic circuits.
    • P/Ns 030M320R-F and 030M320R4-F provide simultaneous NO and NC
      isolated outputs from a Dual-Pole MOS Relay which can sink up to
      100 mA to drive heavy loads.
    • Jumper sets trigger speed to 1,000, 2,000 or 4,000 PPM.
    • Can drive two single LEDs or one bi-colored LED.
    • Compatible with any SmartFan speed controller.
    • Small size of 3.5” X 1.5” permits mounting in small spaces within fan trays, etc.
    • RoHS 6/6 compliant
