10pcs/lot Relay DSP1DC5VRF 5V 6pins Key benefits Simple, reliable way to switch circuits using a lowvoltage 5V control signal. Provides electrical isolation between control electronics and the switched load, protecting sensitive microcontrollers and sensors. Compact 6pin design makes it easy to install on PCBs or in relay sockets for quick replacement and modular designs. Supplied as a set of 10, convenient for prototyping, small production runs, and work. What this relay does and why you need it The DSP1DC5VRF is an electromechanical relay with a 5V DC coil. It lets you control highervoltage or highercurrent circuits from a lowvoltage control line while keeping the two circuits electrically separated. Use it whenever you need reliable on/off switching driven by digital outputs (for example, from microcontrollers, logic boards, or lowvoltage control panels). Key attributes Model: DSP1DC5VRF Coil voltage: DC 5V Pins: 6pin configuration for PCB mounting or compatible relay sockets Quantity: 10 pieces per lot Functionality: Electromechanical switching and isolation driven by a 5V coil Compatibility and installation notes Designed to work with 5V logic and control systems. Verify coil voltage compatibility before connecting. 6pin layout is intended for standard PCB mounting or matching 6pin relay sockets; confirm pin mapping with your wiring diagram. Use appropriate flyback diode or suppression on the coil if integrating into DC control circuits, and follow good PCB layout and grounding practices for reliable operation. Example use cases Microcontroller projects: Drive external loads such as lamps, small motors, or fans from Arduino, Raspberry Pi (with appropriate drivers), and other 5V control boards while keeping the control electronics isolated. Industrial and automation control panels: Integrate into control boards where a compact, replaceable 6pin relay is needed for switching and isolation of control and power circuits. Alarm and security systems: Use the relay to switch sirens, sensors, or auxiliary circuits controlled by a 5V detection or logic output. Practical tips Confirm the load voltage and current requirements and ensure they match the relay contact ratings provided by your supplier. When switching inductive loads, include suitable suppression (snubbers or diodes) to protect contacts and driving electronics. Test wiring on a bench with proper power limits before deploying into final systems. This 10piece lot of DSP1DC5VRF relays gives you a consistent, compact solution for repeated switching and isolation tasks in electronics projects, repairs, and smallscale production.
