Relay Module 5V (4 Channel) Active Low Trigger

From the shop's description

Relay Module 5V (4 Channel) Active Low Trigger The 5V 4-channel relay module provides four independently controlled electromechanical relay outputs in a convenient PCB-mounted module. It allows low-voltage digital control signals from a microcontroller or development board to switch external electrical loads that require a separate power source. The module uses active-low triggering, meaning a relay channel is activated when its corresponding input is driven LOW. Each channel provides normally open (NO), normally closed (NC), and common (COM) contacts, allowing the module to be used for switching, isolation, and control applications involving different types of loads. Features: Four independently controlled relay channels. Active-low trigger operation. Electromechanical relay switching. Screw terminals for load connections. LED indicators for relay status. Suitable for microcontroller control. Separate low-voltage control and load connections. Compact PCB module design. Easy installation and wiring.
