Phoenix Contact PSM-ME-RS232/RS485 Interface Converter | RS-232 to RS-485 Signal Converter | DIN Rail Mount | 24 V DC | Order No. 2744416

The Phoenix Contact PSM-ME-RS232/RS485 is a robust and compact interface converter designed to seamlessly bridge the gap between RS-232 and RS-485 communication standards. This DIN rail mounted unit is essential for modernizing legacy systems, extending communication distances, and creating multi-drop networks in industrial environments.

Ideal for applications in automation, process control, and building management, this converter solves critical connectivity challenges. It allows equipment with older RS-232 ports (like PCs, HMIs, or controllers) to communicate with modern RS-485 based devices (such as drives, sensors, and PLCs) over much longer distances—up to 1200 meters.

Key benefits include:

• Extended Range: Convert short-distance RS-232 signals (typically <15m) to robust RS-485, enabling reliable data transmission up to 1200 meters.

• Network Expansion: Create multi-drop networks with up to 32 nodes on a single RS-485 bus, reducing wiring complexity and cost.

• Industrial Durability: Designed for harsh conditions with a wide operating temperature range and 24 V DC power supply for industrial control panels.

• Easy Installation: Simple DIN rail mounting and clear LED status indicators (PWR, TXD, RXD) for quick setup and diagnostics.

• Signal Isolation: Provides galvanic isolation to protect sensitive equipment from ground loops, voltage surges, and electrical noise.
