Phoenix Contact Phoenix - Interface Converter - PSM-ME-RS485/RS485-P - 2744429

Features
 •The performance and availability of bus systems can be significantly increased by using repeaters
 • In addition to electrical isolation, bus segmentation with repeaters makes it possible to multiply the permissible coverage of the network and to extend the number of devices
 • The PSM-ME-RS485/RS485-P compact repeater is for universal use in RS-485 2-wire bus systems
 • The device supports bus systems that rely on the UART/NRZ data format with a character length of 10 or 11 bits
 • Transmission speeds of up to 1.5 Mbps
 • Space-saving slim 22.5 mm device
 • High-quality 3-way isolation between all interfaces
 • Integrated, connectable termination resistors
 • All connections can be plugged in using a COMBICON screw terminal block
 • Shipbuilding approval in accordance with DNV GL
