ProductDescription : description?
1. Adopt brand new original optocoupler.
2. The limit switching frequency is 20KHZ.
3. Widely used, it can be used for signal isolation, level conversion between MCU, PLC and other signals, PNP, NPN signal to NPN signal, signal level voltage conversion and other purposes.

Module terminal and definition:
signal input
1+: The first signal input positive
1-: The first signal input negative
2+: The second signal input positive
2-: The second signal input negative
3+: The third signal input positive
3-: The third signal input negative
4+: The fourth signal input positive
4-: The fourth signal input negative
power input
VCC: DC power supply positive (*)
GND: DC power negative
Signal output
O1: The first signal output (Output)
O2: The second signal output (Output)
O3: The third signal output (Output)
O4: The fourth signal output (Output)
(*) : The DC power supply is the same as the signal output voltage. For example, if the signal is 24V to 5V, then VCC = 5V input.

Module wiring: (The output signal is a few V, the module power supply uses a few V. The following uses "24V to 5V" as an example, the signal conversion of the remaining voltages are similar)
