RS232 to RS422/RS485 or 20mA converters, DIN-rail

Compact industrial RS232 to RS422/RS485 and 20mA converters are valuable components in industrial automation systems and process control systems. They allow users to convert serial communications between different formats and protocols, while maintaining data integrity and protecting against ground loops.

One of the most important features of these converters is the isolation between the RS232 and RS422/RS485 and 20mA ports. This isolation is critical to prevent ground loops and to protect the RS232 port of PCs, PLCs or controllers from electrical interference. Some inverters even offer 3-way isolation, meaning there is isolation between the power supply and all serial ports, further increasing reliability.

For RS485 half-duplex connections, there are converters that automatically switch between sending and receiving data. These inverters have the addition ADE (Auto Drive Enable) or ATA (Auto Turn Around). This simplifies communication configuration and ensures that data is passed correctly between the devices.

In addition, programmable inverters are available for RS485 or RS422 applications with special protocols. This makes these inverters particularly flexible and adaptable to different industrial applications and communication requirements.

The fact that these inverters are suitable for DIN rail mounting makes them ideal for industrial environments where space is often limited. They can be easily integrated into switch cabinets or control panels.

In short, compact industrial RS232 to RS422/RS485 and 20mA converters are essential components for maintaining reliable serial communications in industrial environments. They provide isolation, automatic switching and programmable options to meet different communication needs, and contribute to the smooth operation of automated processes and control systems.
