Description
Product Description
The 6 Channel 12V Relay Module with Optocoupler is a premium interface solution designed to provide reliable, isolated, and flexible control for 12V-based systems. It serves as a robust bridge between 12V control logic from PLCs, industrial controllers, or automotive systems and a wide range of high-power AC or DC loads. The core innovation lies in its integration of advanced optocouplers for all six channels, creating a critical 2500V electrical barrier that isolates your sensitive control circuitry from the potentially noisy and hazardous high-voltage/current load side. This ensures complete protection against damaging voltage spikes, ground loops, and electrical interference, guaranteeing the longevity and stability of your control equipment.
Engineered for versatility, the module features individually selectable high-level or low-level trigger logic for each channel via simple onboard jumpers. This allows seamless compatibility with any 12V sourcing (PNP) or sinking (NPN) control signals. With six industrial-grade relays capable of handling substantial currents, clear dual-LED status indicators per channel, and secure screw terminal connections, this module is the ideal choice for building sophisticated multi-zone control systems, industrial machine interfaces, and complex automation projects where safety, reliability, and flexible signal handling are paramount.
Key Features
-
Six-Channel Opto-Isolated Design: Each of the six independent channels is protected by a dedicated optocoupler, providing 2500Vrms of isolation to safeguard 12V control systems from load-side electrical noise and transients.
-
Dual Trigger Logic Selectable: Each channel can be individually configured for High-Level (active on +12V) or Low-Level (active on 0V/GND) trigger via a simple jumper, ensuring compatibility with all 12V PLCs and controllers.
-
Industrial 12V Compatibility: Designed for direct integration into standard 12V DC control environments, including factory automation, automotive applications, and control panels.
-
High-Current Relay Outputs: Features six robust electromagnetic relays with SPDT contacts, each rated to switch loads up to 10A at 250VAC or 30VDC.
-
Comprehensive Status Indicators: Dual LEDs per channel provide clear visual feedback: one indicates the opto-isolator input status, and the other confirms the physical relay coil activation and contact switching.
-
Secure & Professional Connections: All high-power load and DC power inputs utilize reliable screw terminals for safe, vibration-resistant wiring suitable for industrial and vehicular installations.
-
Integrated Protection: Includes flyback diodes across each relay coil to suppress inductive voltage spikes, protecting the driving circuitry and enhancing module longevity.
-
Compact, High-Density Layout: Efficient PCB design packs six fully isolated relay channels into a compact form factor, saving space in control cabinets and enclosures.
