Note
●
If powered by MINI USB, do not use external output function.
●
When both input 1 and input 2 are valid, input 1 is valid, input 2 is neglected.
●
When using pulse input, please note pulse width and pulse interval shall be above 500ms.
●
Please choose the relay with DC12V and rated current below 40mA to connect to external output.
●
Please do not use relay with built-in diode. If the wiring is wrong, it may be damaged.
