Yes. The ICP DAS USA I-7561, I-7561U, and TM-7561 USB to RS-485 converters all provide a built-in 5 Volt bias voltage across the RS-485 port, which helps maintain stable communication and prevents floating bus conditions in Modbus RTU networks. The TM-7561 is a dedicated USB-powered RS-485 converter designed specifically for Modbus Client and Modbus Server devices, making it ideal for configuration, testing, and permanent installations. These converters support Windows 7, Windows 10, Windows 11, and Linux drivers, enabling easy integration with PCs, HMIs, and industrial gateways for data acquisition and control applications.
