Compact 4.5V DC 8‑Pin Relays — 10 Pack (UA24.5NU / UA24.5NU) Reliable lowvoltage switching for prototypes, repairs, and small control systems. These UA24.5NU relays accept a 4.5V DC coil input (DC4.5V) and come in a standard 8‑pin package, supplied as a set of 10 pieces for easy replacement or batch projects. Key benefits Lowvoltage operation: Designed for systems and controllers that provide a 4.5V DC drive signal, enabling direct switching without additional driver voltage. Simple integration: 8‑pin format fits common PCB footprints and relay sockets for fast assembly, testing, and replacement. Costeffective pack: Ten identical relays provide spares or multiples for multichannel designs and work. Versatile switching: Use to isolate control logic from load circuits and to switch power, signals, or control lines in a wide range of small electronics applications. Key attributes Model: UA24.5NU (also listed as UA24.5NU / UA2 4.5NU) Coil voltage: 4.5V DC (DC4.5V) Pin count: 8 pins for standard PCB or socket mounting Quantity: 10PCS included Typical applications Home automation and hobby electronics: Interface microcontrollers or lowvoltage control boards to external devices such as lights, motors, or actuators. Prototyping and development: Ideal for breadboard/PCB projects and lab testing where multiple identical relays are needed. and replacement: Keep as spare relays for repairing equipment that uses 4.5V relay coils and 8‑pin relay sockets. Installation and compatibility notes Designed to work with 4.5V DC control signals; verify your drive voltage matches the coil rating before installation. Standard 8‑pin layout suits common relay footprints—confirm pin mapping and contact configuration for your circuit prior to soldering. Supplied as a pack of 10 identical relays for convenience in multi‑channel designs or maintenance.
