The TCC-80 and TCC-80I media converters deliver full RS-232 to RS-422/485 signal conversion in a compact design – with no external power required. They are ideal for space-constrained industrial applications that require simple, reliable serial communication. The TCC-80I variant adds 2.5 kV optical isolation for enhanced protection in noisy environments.

Automatic baudrate detection and RS-485 direction control simplify installation by removing the need for external programming or flow control logic. The LED indicator provides a quick check to confirm the port is supplying adequate power.

Features:

• Power supplied via RS-232 or 5–12 VDC external adapter
• Supports RS-422, 2-wire and 4-wire RS-485
• ADDC (automatic data direction control) and baudrate auto-detection
• 2.5 kV isolation on TCC-80I models
• Integrated 120-ohm termination resistors
• Compact IP30-rated enclosure
• Port power status LED
