Relay (6V) Songle SRD-6VDC-SL-C

The Relay (6V) Songle SRD-6VDC-SL-C is a sealed electromechanical PCB relay with a 6 V DC coil and one changeover contact. A small current through the coil switches a separate load circuit of up to 10 A, so it is used to turn lamps, pumps, fans and other loads on and off from a microcontroller, timer or 6 V battery circuit. It belongs to the same SRD family used on most relay modules.

Relay (6V) Songle SRD-6VDC-SL-C Specifications

Relay (6V) Songle SRD-6VDC-SL-C Applications

• Switching lamps, pumps, fans and solenoids from a control circuit
• Projects powered by a 6 V battery pack, such as 4 × AA cells
• Building your own relay boards and control panels
• Timer, thermostat and alarm circuits
• Electronics education and repair of equipment that uses 6 V relays

What's in the Box

• 1 × Songle SRD-06VDC-SL-C 6 V relay

Tip: The coil needs about 60 mA, more than an Arduino pin should supply, so drive it through an NPN transistor such as the BC547 or 2N2222 and fit a 1N4007 diode across the coil to absorb the switch-off spike. Take great care with mains wiring and keep it fully insulated.
