Relay Board 8ch

The PIERRE Pro Relay Board 8ch allows efficient switching of multiple high-power devices such as lights, motors, and appliances. Each relay channel supports a load capacity of up to 2.5A, with clear labels for inputs and outputs to simplify installation. 

The board features reverse polarity, over-voltage, and short circuit protection to ensure safety. It operates with a 12V DC input and is designed to fit standard DIN rail mounts, enabling easy integration into control systems. Built with durable PCB materials, the board ensures reliable performance in various environments.

The PIERRE Pro Relay Board 8ch using solid-state relay (SSR), an electronic switching device that uses semiconductor components (such as triacs, thyristors, or transistors) instead of mechanical contacts to switch a load on or off.

Short Technical Description:

A solid-state relay works by receiving a low-power control signal (typically DC), which activates an optocoupler (opto-isolator). The optocoupler provides galvanic isolation between the control and load sides. When triggered, the internal semiconductor switch (like a triac for AC loads) conducts, allowing current to flow through the load. When the control signal is removed, the device stops conducting.

Key Characteristics:

• No moving parts → silent and durable

• Fast switching

• Electrical isolation between input and output

• Low control voltage with capability to switch high-voltage loads
