Multle usage Used for signal isolation, PLC level conversion, PNP/NPN to PNP signal, signal level voltage conversion, etc. 2. Use Taiwanese coupler 3. Limit switching frequency up to 10KHZ 4 Arduiuo NANO UNO esp8266 raspberry pi 5. Size:38mm*20mm*5mm 6. Weight:3.9g Module wiring terminal and definition: Function Label Instruction Signal Input 1+ The first signal input anode 1- The first signal input cathode 2+ The second signal input anode 2- The second signal input cathode 3+ The third signal input anode 3- The third signal input cathode 4+ The fourth signal input anode 4- The fourth signal input cathode Power Input VCC DC power anode(*) GND DC power supply cathode Signal Output O1 The first signal output O2 The second signal output O3 The third signal output O4 The fourth signal output (*):The DC power supply is the same as the signal output voltage. For example, if the signal is fro.3V to 5V, then VCC=5V input.
