This product is designed for monitoring the speed of two PWM fans. If the set minimum speed is undershot for example contamination or a fan failure corresponding signal and LED outputs are activated, which can be evaluated externally. Using a potentiometer, the maximum speed of both fans can be adjusted. A customized software adjustment, for example changing the minimum speed threshold, can be optionally offered by us.
- Monitoring of 2 fans (14V DC to 30V DC)
- Maximum fan speed adjustable
- Connection option for two external status LEDs
- 2* digital outputs for fan status
- 4* pluggable screw terminals for wiring connection
- DIN rail mounting
