SDTSH124DM (SDT SH 124DM / SDTSH124DM) 24VDC Normally Open Relay — 10 Pieces Why you need this relay Reliable 24VDC switching for control systems: these relays provide a simple, dependable way to switch circuits driven by a 24V DC control signal. Ready for inline or modular installations: the compact 4pin package fits standard 4pin relay sockets and PCB footprints, making replacement or expansion straightforward. Bulk pack for projects and maintenance: supplied as a set of 10, ideal for repairs, prototype builds, or small production runs. Key features and attributes Model: SDTSH124DM (also listed as SDT SH 124DM and SDTSH124DM) Coil voltage: 24V DC (DC24V) Contact configuration: Normally Open (NO) Contact rating: 10 A switching capacity Pin count: 4pin package Quantity: 10 pieces per pack What this relay does When the 24V DC coil is energized, the Normally Open contact closes to allow current flow up to the rated 10A. When the coil is deenergized, the contact returns to the open position. This makes it ideal for controlling loads only when a control signal is present. Compatibility and installation notes Designed for 24V DC control circuits and compatible with standard 4pin relay sockets and PCB mounting patterns. Compact 4pin footprint allows quick replacement of similar relays without significant wiring changes. Confirm your circuit's voltage and current requirements before installing to ensure safe operation within the 24V coil and 10A contact rating. Typical applications Industrial control panels: switch motors, solenoids, or indicator circuits controlled by 24V logic or PLC outputs. Vehicle and equipment systems that use 24V DC control signals: control lights, fans, or auxiliary devices on trucks or heavy equipment that operate at 24V. Building automation and security: interface 24V sensors, control modules, or remote outputs where normally open switching is required. Package contents 10 x SDTSH124DM 24VDC Normally Open relays (4pin, 10A) Practical tips Use a relay socket or proper PCB footprint to simplify replacement and reduce soldering stress. Verify wiring for coil and load connections before applying power. Do not exceed the 10A contact rating to maintain longterm reliability. This set delivers a straightforward, economical solution for 24V DC switching needs, matched to the SDTSH124DM family and supplied in a convenient 10piece quantity for maintenance and project use.
