Review on Timer Relay Module 0~60M DC12V 30A Delay On/Off Switch Timer Relay Adjustable Multifunctional Timer Relay Module For Timer Operating Equipment by Duane Hayes

When the package arrived the only thing in the package was the board sealed in an antistatic bag!Wiring is straight forward as far as the board supply voltage.The relay output is wired in a logical layout.BUT!When you hook-up the trigger input you may think you have to supply a 3-15 vdc trigger signal to the board. This would be WRONG. The trigger positive terminal sources 12 vdc to the field mounted trigger device!The timing chart!I have attached what I could find from other sites that sell this device. It appears to do a standard binary count up to 10 seconds but after that , who knows?Beware there appears to be no support for this device so you are on your own!
