Product Description

SRD9VDC 10A 250VAC 5Pin Power Relay

Low-Voltage SPDT Relay with High Current Capacity

The SRD9VDC is a 10A power relay with 250VAC switching, featuring a 9VDC coil and 5pin SPDT configuration. This relay bridges lowvoltage logic and highpower loads effectively.

Unique 9V Coil Ideal for batterypowered and regulated 9V systems
HeavyDuty Contacts 10A at 250VAC for robust switching
Requires stable 9VDC supply drawing 111mA coil current
Use standard 5-pin relay socket for quick installation
Never exceed 10A or 250VAC contact limits

Connection Guidelines

Proper wiring practices:

  • Use 1.5mm² wire for contact circuits
  • Use 0.5mm² wire for coil
  • Solder within 3 seconds at 350°C maximum
  • Use socket for prototyping convenience
Add freewheel diode across coil for inductive load protection
Install external 10A fuse in series with common contact

Safety Protections

Coil Protection - Diode (1N4007) or TVS recommended

Contact Protection - RC snubber for AC, diode for DC loads

Overload Protection Use 10A fastblow fuse

Never switch inductive loads without arc suppression
Maintain 25°C to +70°C ambient operating range
Do not exceed 1500VAC isolation voltage

Troubleshooting

Relay chattering:

  • Verify stable 9VDC supply voltage
  • Check for loose connections
  • Avoid long control wires without shielding

Contact overheating:

  • Reduce load current
  • Check contact resistance
  • Avoid frequent switching under load
