Product Description

The PSM-ME-RS232/RS485-P is an interface converter from Phoenix Contact that bidirectionally converts RS-232 (V.24) signals to RS-422 (V.11) and RS-485 standards. Designed for DIN rail mounting, it facilitates communication between devices with different serial interfaces, supporting both 2-wire half-duplex and 4-wire full-duplex configurations. The converter operates over transmission speeds ranging from 1.2 kbps to 115.2 kbps and features electrical isolation between the power supply, RS-232, and RS-422/RS-485 interfaces, ensuring safe decoupling of potentials with 2 kV isolation.
