By adjusting the reference voltage adjustment poten tionmeter to generate the reference voltage,Sensor and pressure resistance of the voltage comparing with reference voltage,To achieve high and low levels of comparison results output.
Applicable to capture cards,microcontrollers, PLC and other testing, you can drive relays and other equipment.Module sensors can be connected to many types of sensors.Such as resistance of the sensor:NTC type thermistor temperature sensor, photosensitive photosensitivity sensor,vibration sen sors etc.
Increase the output current capability, the output can drive the relay, LED and other equipment.
With power indicator and output level indicator(when output low indicator light on, output is high indicator light off),working status at a glance.
Super mini size.
Board edges using circular design, to prevent scratches.
Power supply voltage:DE3-30V
Switch output:output high level is the dame of power supply voltage, and the low level is zero volts.
The reference voltage adjustment range:the minimum value is 0V, the maximum value is equal to the supply voltage.
Positioning hole spacing:31mm
