Nishanth Technologies offers reliable industrial serial communication converters designed for seamless integration, stable performance, and superior protection in automation and control environments.
The TCC-80/TCC-80I series provides complete signal conversion between RS-232 and RS-422/485 without requiring an external power source. These compact, port-powered converters are ideal for industrial automation systems, PLC communication, and control applications.
The TCC-80/TCC-80I converts RS-232 signals to:
RS-422 (4-wire full duplex)
RS-485 2-wire (half duplex)
RS-485 4-wire (full duplex)
The converter operates without an external power supply (external power is supported if required), making installation simple and efficient.
With automatic data direction control, the RS-485 driver is enabled automatically when the circuit senses RS-232 TxD output. This eliminates the need for programming to manage transmission direction.
The TCC-80I model features 2.5 kV isolation protection and is recognized as one of the first high-speed, port-powered converters offering this level of isolation. Additionally, 15 kV ESD protection safeguards the device from electrostatic discharge damage.
The patented LED port power indicator (TCC-80I) allows users to easily verify whether sufficient power is being received.
The TCC-80/TCC-80I series ensures stable and long-distance serial communication in industrial environments.
Key protection features include:
15 kV ESD protection
Optional 2.5 kV isolation (TCC-80I)
Automatic direction control for simplified integration
Its rugged design makes it suitable for continuous 24/7 operation in high-noise industrial conditions.
The converter functions as:
A complete RS-232 to RS-422/485 signal converter
An automatic RS-485 transmission direction controller
An optional electrical isolation barrier (TCC-80I)
It seamlessly integrates into PLC, SCADA, and industrial control networks without requiring configuration or software programming.
