Frequently asked questions
What is the price of 4078-DC12V-SHG Signal Relay Dual-Channel 12VDC 2A 8-Pin in Egypt?
4078-DC12V-SHG Signal Relay Dual-Channel 12VDC 2A 8-Pin currently costs 25 EGP in Egypt.
Where can I buy 4078-DC12V-SHG Signal Relay Dual-Channel 12VDC 2A 8-Pin in Egypt?
4078-DC12V-SHG Signal Relay Dual-Channel 12VDC 2A 8-Pin is available from Makers Electronics. Compare the offers above to find the best price.
Do I need a flyback diode?
Yes. The coil is inductive, so it produces a voltage spike when switched off. Place a flyback diode such as 1N4007 across the coil, with its cathode toward the positive supply, to protect the driver transistor.
Can I drive it directly from an Arduino pin?
No. A 12 VDC coil needs a 12 V supply and usually more current than a microcontroller pin can provide. Use a transistor or MOSFET powered from 12 V, with the microcontroller pin controlling its base or gate.
