Module relais RS485 à 1 canal 5-32 V 4800/9600/19200

Résumé

• Electrical Controller Device: 1 channel relay module is a kind of electric appliance that makes a predetermined step change of the controlled quantity in the electric output circuit when the change of the input quantity (excitation quantity) reaches the specified requirement.
• Automation and Safety: Typically used in automated control circuits, this relay board is pretty much an automatic switch, controlling large currents with minor ones. It plays a significant role in automatic adjustment, safety guard, and circuit conversion, providing more convenience and security.
• Interactive Function: This module has an interactive relationship between the control system (also known as input circuit) and controlled system (or output circuit). It forms a responsive unit that works in an interlinked manner for better functionality.
• Stable and Reliable Configuration: This relay module with optocoupler is equipped with a robust and stable 8 bit MCU and RS485 protocol chip, ensuring longevity and unwavering performance.
• Standard Protocol: Adopting the standard for RTU format of the RS485 protocol, this relay switch can achieve 1 way input signal detection and 1 way relay output. It's ideal for digital quantity detection or power control situations.
