Every relay is paired with an LED indicator for quick visual feedback of relay status. The provision of screw terminal blocks and mounting holes simplifies installation and wiring. Supplied mounting screws facilitate secure attachment to most surfaces, enhancing practical usability.

Industry-Leading Performance and Longevity

Designed for heavy-duty operation, each relay can handle up to 10A at 250V AC or 30V DC, with a mechanical life expectancy of more than 10 million actuations. The board maintains high insulation resistance and dielectric strength, supporting industrial-grade reliability in environments ranging from -20C to +70C.

FAQs of Relay Interface Card Board:

Q: How do I select the appropriate number of relay channels for my application?

A: The board is offered in 4, 8, and 16 channel models. Choose the version that matches the number of independent loads or devices you wish to control. For expansion or complex automation systems, opting for a higher channel count provides more flexibility.

Q: What input control signals are compatible with this relay interface card board?

A: The board supports DC control signals at 5V or 12V, compatible with standard TTL logic. Control signals should be low-level trigger, with each input protected by opto-isolation to prevent electrical interference.

Q: Where can this relay card board be mounted for industrial use?

A: It features PCB mounting holes and includes screws, making it suitable for installation within control panels, enclosures, machine frames, or industrial equipment where secure and accessible placement is required.

Q: What process is used to achieve electrical isolation between control and relay sides?

A: The card employs opto-couplers (photocouplers) for each relay channel, ensuring electrical isolation between the input control logic and the relay load output, which protects sensitive circuitry from voltage transients.

Q: How does the LED indicator system benefit users during operation?

A: Each relay channel is equipped with a dedicated LED indicator, making it easy for users to visually confirm the status of each relay (active/inactive) at a glance, streamlining troubleshooting and operational monitoring.

Q: What are the typical usages of this relay interface card board?

A: This relay board is commonly employed in industrial automation systems, remote equipment control, signal switching, and interface circuits requiring rugged relay output for motors, lights, or other high-current devices.

Q: What advantage does the FR4-grade, glass epoxy PCB material offer?

A: FR4-grade glass epoxy provides excellent thermal, mechanical, and electrical properties, ensuring long-term reliability, robust insulation, and resistance to environmental factors, essential for industrial settings.
