Model / Compatibility ZJ DS2YS series electromagnetic relay — available in DS2YSDC5V, DS2YSDC12V, and DS2YSDC24V coil voltages. This listing is for 1 piece (1Pcs) of the DS2YSDC12V size. 8PIN package fits standard 8pin relay sockets and PCB footprints. Key benefits — why you need it Isolates control electronics from higherpower circuits, protecting sensitive microcontrollers and logic boards. Choose the coil voltage that matches your control system: 5V for logic/microcontroller projects, 12V for common control systems, 24V for many industrial applications. Simple, dropin replacement for equipment using the DS2YS relay family — reduces downtime and simplifies maintenance. What makes it useful and unique Standard 8pin DS2YS footprint ensures wide compatibility with relay sockets and PCB layouts. Multiple coil voltage options (DC5V / DC12V / DC24V) let you select the correct relay for your project without redesigning the control circuitry. Singlepiece (1Pcs) makes it easy to test, , or keep as a spare part. Key attributes Model: DS2YSDC12V (this item) Series: DS2YS (also available as DS2YSDC5V, DS2YSDC24V) Coil voltage options: DC5V, DC12V, DC24V Pin count: 8PIN — compatible with standard 8pin sockets and PCB footprints Quantity: 1Pcs Branding/alternate references: ZJ, DS2YS5V, DS2YS12V, DS2YS24V Functionality and performance Electromechanical switching for reliably controlling external loads from a lowvoltage control signal. Designed for straightforward PCB mounting or socket use with standard 8pin layouts. Suitable for switching tasks where galvanic isolation between control and load circuits is required. Typical applications / use cases Home automation and lighting control: use the DS2YSDC12V relay to switch lighting circuits or motorized shading devices controlled by a 12V system. Control boards and industrial automation: integrate the DS2YS series into PLC interfaces, relays arrays, or control panels requiring a 24V or 12V coil option. DIY electronics and microcontroller projects: the 5V version is a convenient choice to interface Arduino, Raspberry Pi (with driver), or other logiclevel controllers through an 8pin relay socket. Installation tips Verify coil voltage matches your control supply before installation. Use an appropriate driver or transistor and flyback diode when driving the coil from a microcontroller or logic output. Confirm pin orientation and socket wiring against the device schematic to prevent miswiring. What you get One (1) DS2YSDC12V relay, 8pin, compatible with the DS2YS family (also available in DC5V and DC24V variants). Ideal for replacement, prototyping, and system upgrades where a standard 8pin relay is required.
