- The power supply: 12V.
- Press the button on the board or the external button to let the relay module pull or close. Press the pull button and then press the button to trigger the low level. The relay is off when the power is turned back on.
- The maximum current of the secondary output of the relay is 10A, which means that the maximum operating current of the controlled circuit or equipment cannot be greater than 10A, and it can be connected to the normally open or normally closed end according to its own needs.
- The welding position of the external suction indicator light is reserved, and the welding indicator light is also welded on the board.
- Module size: 53.8mm x 32.6mm x 17mm.
One-button two-state relay module, the power supply is negatively connected and will be burned off, no power supply reverse protection.
Low level control: that is, the signal line and the ground touch is a trigger signal.
Using the design double-panel PCB.
Ballast used for tension and stable.
With reverse cut protection Reverse polarity, a diet is low in time without damage to the product.
The use of real Songle relay control loads.
Trigger can also be an external trigger switch, the product is fitted with a good seat and lead wires, more convenient to use.
Power supply: 12V DC
