Serial Converters
Industrial serial converters are used to bridge communication between different serial interfaces or between serial devices and Ethernet-based networks. These devices enable legacy equipment using RS-232, RS-422, or RS-485 protocols to communicate over longer distances, integrate into modern networks, or operate reliably in electrically noisy environments. Serial converters play a critical role in maintaining compatibility across mixed-protocol automation systems.
Many industrial applications rely on serial converters to translate RS-232 signals to RS-422 or RS-485, allowing for differential signaling and improved noise immunity. RS-485 configurations also support multi-drop networking, making them well-suited for SCADA systems, distributed control networks, and factory automation. Serial-to-Ethernet converters further extend connectivity by enabling serial devices to communicate across TCP/IP networks without requiring major system redesigns.
Manufacturers such as Moxa offer industrial serial converters designed for rugged operation and long-term reliability. Common features include automatic data direction control for RS-485, electrical and optical isolation, surge protection, and DIN-rail or panel mounting options. Many models support plug-and-play installation and driver-free operation, simplifying deployment while ensuring stable communication in harsh industrial environments.
FAQs
Q: What is an industrial serial converter used for?
Industrial serial converters are used to translate signals between different serial standards or between serial devices and Ethernet networks, enabling compatibility with legacy and modern systems.
Q: Why convert RS-232 to RS-422 or RS-485?
RS-422 and RS-485 support longer communication distances and offer better noise immunity than RS-232, making them more suitable for industrial environments.
Q: What is a serial-to-Ethernet converter?
A serial-to-Ethernet converter allows serial devices to communicate over an Ethernet network using TCP/IP, enabling remote access and centralized monitoring.
Q: Do industrial serial converters provide electrical isolation?
Many industrial serial converters include electrical or optical isolation to protect equipment from voltage surges, ground loops, and electrical noise.
Q: Are serial converters easy to install?
Yes, many models offer plug-and-play functionality, driver-free operation, and flexible mounting options, making them easy to integrate into existing systems.
