8-Channel 5V relay module with wide 5–40V input range, LM2576 power regulation, ULN2803 driver, and screw terminals for easy wiring.

Features :

8-Channel relay module using T73 relays (rated 10A for resistive loads; recommended ≤ 5A for inductive loads).
Wide input voltage range: 5V to 40V selectable via 3-pin jumper.
5–7V mode: Direct input to relays.
7–40V mode: Onboard LM2576 buck converter outputs stable 5V.
Relay coil voltage: 5V for all channels.
Compatible trigger signal range: 3V to 24V.
Integrated ULN2803 driver IC with built-in flyback diodes for relay protection.
Additional reverse polarity protection diode on power input.
Each relay has LED indicator for status visualization.
Output terminals: 3-pin screw connectors (NC, COM, NO) per relay.
Input & power via 10-pin screw terminal (2 power pins + IN1 to IN8).
High-quality PCB with white silkscreen legend for easy wiring identification.
Four mounting holes (Ø 3.5 mm) for secure installation.

Some of the possible applications:

Very good to use it with motor switching control or pump starting applications with your microcontrollers, Arduino boards, or PC port.
