Pack of 5 power relays designed for reliable switching in control, automation and DIY electronics. Available in common coil voltages and built to handle moderate loads, these 9431C series relays provide a compact, fivepin SPDT (single pole changeover) solution for diverse switching needs. Key benefits Simple, reliable switching: 1C (SPDT) contact arrangement lets you switch one circuit between two outputs or use as a standard NO/NC relay. Ready for multiple control voltages: available coil voltages of 5V, 12V and 24V make these relays compatible with microcontrollers, automotive systems and industrial control lines. Compact, serviceable package: fivepin layout simplifies PCB or socket mounting and replacement in existing relay sockets. Sufficient load capacity for many applications: 12A rated contacts are suitable for lights, motors, solenoids and other loads within the specified rating. What's included and model options Quantity: 5 pieces Models / Coil voltages: 9431C5DS (5V coil), 9431C12DS (12V coil), 9431C24DS (24V coil) Size: 9431C12DS (as listed) Key attributes Contact configuration: 1C (single pole changeover / SPDT) Pins: 5pin design for common PCB or socket mounting Rated contact current: 12A Coil voltages: 5V, 12V, 24V (select the model that matches your control voltage) Models: 9431C5DS, 9431C12DS, 9431C24DS Package: set of 5 relays (Size : 9431C12DS) Applications / use cases Microcontroller projects and relay boards: Use the 5V or 12V coil versions with appropriate driver transistors or relay driver ICs to control lights, pumps or motors from Arduino, Raspberry Pi (with level shifting/drivers) and other controllers. Automotive and vehicle systems: The 12V and 24V coil models work with typical automotive and commercial vehicle electrical systems to switch accessories, lighting circuits or small motors, keeping switching current away from sensitive control electronics. Industrial control and home automation: Switch AC or DC loads (within the 12A rating) in HVAC controls, motor starters, timers and home automation modules where a compact SPDT relay is required. Installation and usage notes Match coil voltage to your control circuit: choose 9431C5DS for 5V control, 9431C12DS for 12V, or 9431C24DS for 24V. Use a suitable driver (transistor, MOSFET, or relay driver IC) when switching the coil from lowcurrent digital outputs; include a flyback diode or suppression for DC coils to protect driving electronics. Ensure the switched load does not exceed the 12A contact rating and account for inrush currents (motors and some lamps can draw higher initial current). Confirm pinout and mounting orientation against your PCB or socket before soldering. Why choose these relays Straightforward compatibility with common control voltages and a 12A contact rating make this 5piece set a practical replacement or spare inventory for , prototyping, and smallscale production. Standard 5pin, 1C configuration makes integration into relay modules and legacy designs simple and predictable.
