DONGKER 8-Channel Optocoupler Isolation Board
DONGKER 8-channel optocoupler isolation board can output DC voltage according to the detection result, and the output result can be applied to PLC system and other control devices, which can detect whether there is input power or not. When input power is detected, the output state will change.
Input Voltage: DC 3.3V~5V
Load Input Voltage: DC 1.8V~24V
Output type: NPN / PNP (Low/High level) signal output
Output current: 50mA
Work Temperature: -20℃~85℃
Work Humidity: 10%~85%RH
Size: 72*50*27mm
DONGKER 8-channel optocoupler isolation boards support NPN/PNP (low/high level) signal outputs as well as DC 3.3V~5V inputs, with applications ranging from DC power testing, PLC control systems, and equipment alarms.

Device is as expected. A must for my Beagle Bone system. I fried my first BBONE because I failed to Isolate the IO.

This board seems well made and if of acceptable quality. It works exactly as intended with up to 24V input/output. Well done!

Hooked it up according to the very limited wiring diagram and it does not power on any of the connected output devices. It lights up the LEDs with no load, but connecting to the ground and an output pin with just a simple relay did not do anything and does not power the relay. It's almost like it has no amperage at all, even for a 50mA relay. Could not find any other documentation on any other ways to wire it but the same results happen wiring it PNP inputs or NPN inputs. Would not waste your time.
