The I-7510AR is a high-speed, three-way isolation repeater designed to enhance and extend serial communication networks. It provides robust electrical isolation between the two RS-422/485 ports and the power input circuits, protecting connected devices. Additionally, it offers effective noise suppression and signal waveform enhancement on its RS-422/485 ports, ensuring reliable and high-quality data transmission. Each repeater extends transmission distances by an additional 1.2 km (4,000 feet) at speeds of up to 115,200 bps and overcomes the 256-node limitation of RS-485 systems, enabling larger networks. Furthermore, the I-7510AR facilitates seamless conversion between four-wire RS-422 and two-wire RS-485 signals, providing exceptional flexibility in network configuration. This makes the I-7510AR a valuable tool for anyone working with RS-422/485 networks, offering enhanced reliability, extended range, and greater flexibility.



The I-7510AR is exactly the same as the I-7510A, except for the isolation side. The isolation side of the I-7510A is located in the input interface circuit, but the isolation side of the I-7510AR is located in the input and output interface circuit. In other words the I-7510AR is 3-way isolation repeater module.
