I-7513 CR - industrial three-way active RS-485 hub

I-7513 – Active RS-485 Hub with Three Isolated Channels. 

The I-7513 module is a modern solution for RS-485 communication networks, providing reliability, high resistance to interference, and efficient data transmission. The device functions as an active hub and repeater, enabling stable data transmission in a star topology. With three independent channels, the I-7513 optimizes RS-485 network structure, eliminating the risk of signal collisions and increasing resistance to electromagnetic interference.

Compared to traditional RS-485 converters, I-7513 stands out with its triple 3000VDC isolation, which protects both the device and connected systems from overvoltage and potential differences. The device features built-in ESD (Electrostatic Discharge) protection, which further safeguards electronic circuits from sudden voltage spikes. Thanks to these features, I-7513 can be used in high-interference environments, such as industrial plants with strong electromagnetic fields.

Key Features of I-7513

• Three independent RS-485 channels – allows multiple devices to be connected in a star topology
• 3000 VDC isolation – protection against overvoltage and potential differences
• Automatic transmission direction control – no additional software required
• Maximum transmission distance: 4000 m per channel
• Supports data transmission up to 115200 kbps, with adjustable speed
• Supports Modbus RTU standard, ensuring compatibility with automation systems
• DIN rail mounting – quick and easy installation
• Built-in Asic autotuner that automatically optimizes signal quality
• Electromagnetic interference resistance – stable communication in harsh environments
• Triple galvanic isolation – reliable data transmission and device protection

Thanks to these features, the I-7513 is an ideal solution for applications requiring stable RS-485 communication and protection against overvoltage and interference. Its versatility makes it a preferred choice among automation engineers and communication system integrators.

Three Independent RS-485 Communication Channels

The I-7513 is equipped with three independent RS-485 output channels, each with a dedicated driver, enabling flexible network management. Each channel operates independently, allowing communication in different network segments without signal interference. This technology allows multiple devices to be connected efficiently in a star topology, improving the organization of industrial automation systems and enhancing transmission reliability.

The transmission distance for each RS-485 channel is up to 4000 m, making it one of the best options in its class. Moreover, the maximum range at different transmission speeds is as follows:

• At a speed of 115200 kbps – transmission up to 400 m
• At a speed of 9.6 kbps – transmission up to 1200 m

Thanks to the implemented signal isolation mechanism, each channel is separated from the others, meaning that disturbances or failures in one channel do not affect the remaining ones. This solution is especially crucial in industrial systems, where communication stability is key to ensuring smooth system operation.

Practical Applications of I-7513

The I-7513 is widely used in various industrial sectors where reliable and interference-resistant RS-485 communication is essential. Its unique features, such as 3000VDC isolation, support for multiple devices, and long transmission range, make it a crucial component in automation systems, smart buildings, monitoring, and transportation.
