SmartFan TachScan-3 Fan Speed Alarm Contoller Board
SmartFan TachScan-3 Fan Speed Alarm
SmartFan
TachScan-3 is a digital fan speed alarm
that monitors the 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 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.
Product Features - SmartFan TachScan-3 Fan Speed Alarm
P/Ns 030M320 and 030M320R 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 and 030M320R4 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 and 030M3205 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 and 030M320R4 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.
