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
- 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.
