12V Relay UD212NU / UD2 12NU / UD212NU — Microrelay 12VDC, Two Open and Closed Contacts, 8PIN (5PCS) Key benefits Reliable 12V DC switching for control and automation tasks — allows electrical isolation between control circuits and load circuits. Compact microrelay design with an 8pin footprint provides a spacesaving solution for panels, modules, and compact assemblies. Pack of 5 gives spares for maintenance and multiplechannel installations, reducing downtime and simplifying procurement. What this relay does and why you need it The UD212NU (also referenced as UD2 12NU and UD212NU) is a 12VDC electromechanical microrelay designed to switch circuits using two openandclosed contact sets. It solves the common need to control loads from a 12V control signal while keeping circuits isolated and protected. Its compact 8pin configuration makes it suitable for systems where space is limited and where standard 8pin relay sockets or PCB footprints are used. Key attributes Model: UD212NU / UD2 12NU / UD212NU Coil voltage: 12V DC (DC12V) Contact configuration: Two open and closed contact sets (as specified) Pin count: 8PIN for standard installation options Package: 5 pieces per (5PCS) Performance and compatibility notes Designed for generalpurpose switching where a 12V DC coil is required. Compatible with many control circuits and relay sockets that accept an 8pin microrelay form factor. Compact microrelay form allows integration into control panels, relay modules, and prototyping boards where space and pin compatibility matter. Typical applications / use cases Automotive accessory control: Use for switching lights, pumps, or auxiliary devices controlled from a 12V vehicle electrical system. Control panels and industrial automation: Implement as part of relay banks for machine control, signal routing, or interlock circuits where two contact sets are useful. DIY electronics and prototyping: Integrate into Arduino, Raspberry Pi, or PLC projects that require a 12V relay with multiple contact sets for switching relays, motors, or external modules. Practical considerations Confirm socket or PCB footprint compatibility with the 8pin layout before installation. Use appropriate protective measures (flyback diodes, fuses, or suppression circuits) when switching inductive loads. Ordering includes five identical UD212NU relays for consistent performance across channels and replacements. Includes Five (5) × UD212NU / UD2 12NU / UD212NU microrelays, 12VDC, two openandclosed contact sets, 8pin configuration.
