4-channel relay board card is an industrial-grade interface module designed to control high-voltage or high-current loads using low-voltage control signals from devices like PLCs or microcontrollers. Key Features and Specifications:Channels: Typically features 4 independent channels. Input Voltage: Common nominal input coil voltages are 24V DC or 5V DC. Switching Capacity: Can switch maximum voltages up to 230V AC or 30V DC. Limiting continuous current is often around 5A to 12A per contact. Contact Type: Often uses Single Changeover (SPDT or 1CO) contacts. Mounting: Designed for mounting on a DIN 35 carrier rail. Additional Features: May include LED indicators for relay actuation, screw terminals for connections, and protection features like a freewheeling diode across the relay coil. Common Applications: Mains switchingElectrical isolation between high and low power sourcesControlling multiple devices in automation projectsInterfacing with PLCs to manage high-power loads like motors and lights
