Countless Application and Information Sources
When unconnected with the supply power, the state of the module is "NO" [ normal open ], CB and COM are conductive. CK and COM are unconductive.
When connected with the supply power, delay for 0-10s, the module will in the state of "NC" [ normal closed ], CB and COM are unconductive, CK and COM is conductive.
B -Module Properties The relay will not immediately closure after the power is connected, until the delay time over. Then the relay will closures as long as the module power is connected.
The delay time is adjustable (1-20 seconds)
Normally open interface maximum load capacity: AC 0-250V/10A / DC 0-30V / max. 10A
Equipped power indicator light (red), 1 channel relay status indicator light (blue)
With 4 fixed bolt holes, easy to install
The main chip: NE555
Working Voltage: DC 12V
Working current: after relay closures: less than 100mA; before relay closures: less than 5mA
Size: 5.4x2.9x1.5cm(approx)
The relay will delay to closure after the power is connected, Clockwise rotate adjustable resistance can increase the delay time, the delay time is adjustable (1-20 seconds)
Common, normally open, normally closed, they same as a double control switch, when the relay is powered, common and normally open is connected, otherwise common and normally close is connected.
