This is a 5 piece set of OJE SH series power relays. The pack includes relays with different coil voltages to suit a range of control circuits. The models in this set are OJESH105DM (5VDC), OJESH112DM (12VDC) and OJESH124DM (24VDC). All relays use a compact 4pin configuration. Key benefits Isolates and protects control electronics from current loads Enables switching of DC loads using a simple coil drive signal from a microcontroller or control circuit Flexible coil voltage options (5V, 12V, 24V DC) to match your system voltage Includes a 5A rated example variant (OJESH112DM) for reliable switching of typical loads Ready to integrate with standard 4pin relay footprints in compact applications Key attributes Functionality: power relay for switching DC circuits Coil voltage options: 5VDC (SH105DM), 12VDC (SH112DM), 24VDC (SH124DM) Package: 4pin relay design Performance: SH112DM variant specified with a 5A rating Compatibility: suitable for use in small to medium load switching in control boards, automation, and hobby projects Size and form: compact relay unit designed for easy integration into devices and prototyping setups Use cases Microcontroller projects: drive DC motors, pumps, or solenoids from an Arduino, Raspberry Pi, or similar controller Home automation: switch lighting, fans, or vent mechanisms in response to sensors or timers Robotics and automation: control actuators or power stages in small robotic systems What's included 5 relays in the set Models included: OJESH105DM 5VDC, OJESH112DM 12VDC (5A), OJESH124DM 24VDC Each relay uses a 4pin configuration for straightforward integration Notes and guidance The SH112DM variant is rated at 5A; use this model for loads within that rating Verify coil voltage to match your control signal when integrating with microcontrollers or driver circuits For higher current or different load types, select a relay with an appropriate contact rating and coil voltage to suit your application
