| TachScan-9
Fan Monitor Speed Alarm |
|
| SmartFan
TachScan-9
is a digital fan monitor speed alarm for OEM control applications
that monitors the tach pulses from up to nine DC
or AC fans or blowers and provides OR’d pass/fail
signals.
TachScan-9 alarm accepts any supply voltage from 10 to 75 VDC, which is ideal for telecom and other cooling solution applications.
TachScan-9 is compatible with any fan
that provides open collector or
voltage source tach pulses. Three trigger speeds
are selectable by jumper.
| |
If the speed of any
air
mover falls below the trigger speed, alarm signals
are generated. 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 control applications.

| Features |
- Accepts
any supply voltage from 6 to 75 VDC and distributes
power
to DC fans through the same header used
to sense tach pulses. It
can also be used to power the DC tach circuits
built into AC fans.
- Nine
inputs monitor fans with any open collector or voltage
sources tach pulses.
The setting of a dipswitch allows fan headers to be
disabled when fewer than
nine fans are connected.
- Provides
individual outputs for each fan, which can drive logic,
LEDs
or remote optical isolators.
- Provides
OR’d outputs to drive two single LEDs or one
bi-colored LED
- Provides
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.
- Compatible
with any SmartFan speed controller
- Small
size of 5” X 1.5” permits mounting in
small spaces within fan trays, etc.
- Optional
fan fusing is available.
