The PSM-ME-RS485/RS485-P is a compact repeater designed for universal use in RS-485 2-wire bus systems including PROFIBUS, MODBUS, and other proprietary systems. It provides potential separation and range extension through high-quality 3-way electrical isolation between all interfaces, significantly increasing performance and availability of bus networks. The device supports UART/NRZ data format with character lengths of 10 or 11 bits and offers transmission speeds up to 1.5 Mbps. Features include DIN rail mounting in a space-saving 22.5 mm width design, integrated connectable termination resistors, and COMBICON screw terminal connections. The repeater enables bus segmentation to multiply network coverage and extend the number of connected devices while maintaining transmission reliability with integrated surge protection and transient discharge to DIN rail.
