The PIERRE 8-Channel Relay Board is designed for demanding automation and control applications. Utilizing Solid State Relays (SSRs), it ensures silent, reliable, and long-life switching for AC loads.
Technical Highlights
8 Independent SSR Channels: Supports simultaneous and isolated control of multiple AC devices.
Silent Operation: SSRs switch without mechanical movement, eliminating acoustic noise and mechanical wear.
Advanced Leakage Protection: Special circuitry minimizes leakage current, critical for sensitive loads:
Leakage Voltage with Load (e.g., lamp connected): 0V
Leakage Voltage without Load: 4V AC
Compared to industry standards, these values are extremely low, preventing undesired LED flickering or ghost activation.
Zero-Cross Switching: Each SSR integrates zero-cross detection, reducing inrush currents and minimizing EMI (Electromagnetic Interference).
Overvoltage Protection: Safeguards connected loads against AC voltage spikes, enhancing operational stability and device longevity.
Solid State Relay (SSR) Advantages
No Mechanical Contacts: No arc erosion, contact bounce, or mechanical failure modes.
Extended Service Life: Solid-state switching significantly exceeds the operational cycles of electromechanical relays.
Low Switching Noise: Ideal for sensitive environments where EMI and acoustic noise are concerns.
Fast Response Time: Consistent and predictable switching characteristics, essential for precise control systems.
Typical Applications
Smart home automation (lighting, HVAC)
Industrial automation (machinery control, process automation)
Building management systems (BMS)
Security and access control systems
The PIERRE 8-Channel SSR Board offers a highly reliable, low-noise, and maintenance-free switching solution, optimized for systems requiring multiple controlled AC outputs with enhanced electrical protection.

Why use a solid-state relay (SSR)?
Solid-state relays have a longer lifespan and operate silently, making them ideal for many applications.
What happens if one relay in the relay board fails?
PIERRE relay boards use high-quality relays with additional safety features. If one relay fails, you can either replace the entire board or, if possible, use another output.
