PHOENIX CONTACT PSM-ME-RS232/RS485-P 2744416

Phoenix Contact RS232 to RS485/RS422 Interface Converter Description The Phoenix Contact PSM-ME-RS232/RS485-P, order number 2744416, is a high-performance interface converter designed for industrial applications. It provides transparent protocol conversion from the RS232 standard to the RS485 or RS422 standard, enabling long-distance and multi-drop communication. With its robust 3-way electrical isolation (power supply, RS232, RS485/422), it protects connected devices from potential differences and transient interference. The unit is easily configurable via DIP switches for data rate, operating mode, and line termination. Specifications Manufacturer: Phoenix Contact Model: PSM-ME-RS232/RS485-P Order Number: 2744416 Power Supply: 24V DC Interface 1: RS-232 (V.24), D-SUB 9 connector Interface 2: RS-485 (2-wire/4-wire), RS-422, Screw terminals Transmission Speed: Up to 115.2 kbit/s Isolation: 3-way isolation Mounting: DIN rail NS 35 Operating Temperature: -20 deg C to 60 deg C Label Info Type: PSM-ME-RS232/RS485-P Ord-No: 2744416 Sno: 41976452 Application This converter is ideal for integrating legacy RS232 devices into modern RS485 networks, extending serial communication distances, and establishing robust connections in environments with high electrical noise, such as factory floors, process control systems, and building automation. Country of Origin Made in Germany. CO2 Impact Opting for this pre-owned unit prevents the emission of approximately 4.8 kg of CO2, which would have been generated during the production of a new one. This choice supports a circular economy and reduces industrial waste. Availability This is an obsolete item but available from stock. Order now from profideals for expert support and fast delivery. FAQ What is the maximum transmission speed supported by this converter?The PSM-ME-RS232/RS485-P supports data transmission speeds up to 115.2 kbit/s. The speed can be set using the DIP switches on the side of the module, as indicated on the label. Can this module operate in a 2-wire RS485 multi-drop network?Yes, it is designed for both 2-wire and 4-wire RS485 applications. The DIP switches allow you to select the appropriate mode for your network topology. What is the purpose of the DTE/DCE DIP switch setting?The DTE (Data Terminal Equipment) / DCE (Data Communications Equipment) switch configures the RS232 pinout. This allows you to connect the converter to another device using a standard straight-through serial cable, regardless of whether that device is a DTE (like a PC) or a DCE (like a modem), eliminating the need for a null-modem cable.
