EXSYS EX-1339HMVS 8-porttinen USB 2.0 - RS-232/422/485 -sarja-adapteri optisella eristyksellä

The EXSYS EX-1339HMVS stands out by combining eight independently configurable serial ports with 2.5 kV optical isolation and 15 kV ESD protection in a single USB 2.0 device. Unlike basic USB-to-serial converters, this unit supports RS-232, RS-422, and RS-485 standards per port, making it suitable for mixed industrial environments where signal integrity and electrical isolation are critical.

Highlights

• 8 DB9 male serial ports, each software-selectable for RS-232, RS-422, or RS-485
• USB 2.0 high-speed interface (480 Mbps) with a Type-B female connector
• Per-port data rates up to 921.6 Kbps
• 2.5 kV optical isolation and 15 kV ESD protection on all serial lines
• FTDI chipset for reliable driver support across Windows, Linux, and macOS
• DIN-rail and wall-mountable metal housing for industrial installation
• External 5V DC power adapter included

In daily use

The EX-1339HMVS connects to a host computer via USB and provides eight independent serial channels. Each port can be configured for RS-232 full-duplex, RS-422 full-duplex, or RS-485 half-duplex (2-wire) or full-duplex (4-wire) operation. This flexibility allows a single adapter to replace multiple dedicated converters, reducing clutter and cost in control cabinets. The optical isolation protects the host system from ground loops and voltage spikes, while the wide operating temperature range (0°C to 55°C) ensures reliable operation in demanding environments.
