Pin Specification: 5 Pin SPDT (Single Pole Double Switch) Relay, 40A/30A High Switching Capacity Earth (85), VDC (30), Trigger (86), Output N/C (87a), and Output N/O (87).
GREAT VALUE - 10 x 5 Pin Relays You won't buy it anywhere else as long as the price remains the same.
Example installations: light bar, high beam shutter release, parking light and turn signal merge into a single LED, remote start interruption, inverter set for ignition, heating seat retrofit etc.
Easy to store: these are perfect for switching control circuits that run medium power devices. They are configured like some relays of my vehicles. They come in a plastic box and are easy to store. They do not have wiring harnesses, but can be connected to some vehicles or wired as needed.
Caution: the metal lugs are removable, but the relays have a slot to fit the tabs and this small extra width makes the installation very tight.

Main highlights

√ Note: Many microcontrollers may cause the IO to be pulled to high when booting, so we recommend you choose a low level trigger to avoid accidental triggering. On the other hand, a low-level trigger has the advantage that it does not work under load when resetting the system voltage, thus providing greater safety.
√ Application: MCU control, PLC control, industrial area, smart home.
LEDs to indicate the relay status, can be switched with a low level.
Can be controlled directly with a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic)
5 V 8-channel relay module, each relay requires 70 mA for switching (switching capacity AC: max. 250 V / 10 A; DC: max. 30 V / 10 A DC)
