Using high-quality dual-panel design,with power indicator and TTL signal output instructions.
The switching signal having a DO (TTL) output and analog output AO.
TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
Analog output voltage with the higher concentration of higher voltage
There are four screw holes for easy positioning.
Has a long life and reliable stability
Rapid response and recovery characteristic
Input voltage : DC5V Power consumption ( current ): 150mA
DO output : TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ),the maximum concentration of a voltage of about 4V
