The Moxa TCC-80I is a powered serial converter that bridges RS-232 devices to RS-422/485 networks. It’s built for industrial environments where serial lines get plugged, unplugged, and occasionally abused—making it a solid choice for stable conversions and better protection in the real world.

Why We Love This Product

• Converts RS-232 to RS-422/485 to connect legacy devices into multi-drop serial networks
• Powered design supports more reliable operation in permanent installations
• 15 kV serial ESD protection helps reduce failures from static and handling events
• Practical choice for control cabinets, panels, and industrial retrofit projects

How Our Customers Use It

• Connecting RS-232 instruments to RS-485 field buses in plants and utilities
• Upgrading old serial point-to-point links into longer-distance RS-422/485 runs
• Reducing serial comms issues where cabling is long or environments are electrically noisy
• Permanent conversions inside cabinets where stability matters more than “quick test” setups

Choosing Tips

• Choose TCC-80I when you need RS-232 to RS-422/485 conversion with added ESD protection
• If you need isolation between serial sides, pick an isolated converter model instead
• If you only need temporary laptop access, a USB-to-serial adapter may be the simpler approach
