Information About 2744416
The 2744416 is part of the Phoenix Contact PSM-ME interface converter family, developed for reliable serial communication in industrial automation environments. It is constructed with a compact, rail-mountable housing and integrates electrical isolation between data interfaces and the power supply to enhance signal integrity. The converter supports full-duplex communication and transparent protocols, enabling seamless integration with serial devices and fieldbus systems such as Modbus. It is typically used in industrial control, process automation, and infrastructure systems where protocol conversion and electrical isolation are required for stable data transmission.
Key Features:
- RS-232 to RS-422/RS-485 conversion: Enables interoperability between different serial communication standards.
- Electrical isolation: Provides 1.5 kV AC isolation to protect against ground loops and interference.
- Dual transmission channels: Supports simultaneous full-duplex communication.
- DIN rail mounting: Designed for standardized installation in control cabinets.
- Flexible supply voltage range: Operates from 18…30 V AC/DC.
- Long transmission distances: Supports up to 1200 m with shielded twisted-pair cabling.
- Industrial-grade housing: Suitable for harsh operating environments.
The 2744416 delivers the reliability and precision required for isolated serial communication and protocol conversion in industrial automation systems.
