The Moxa TCC-100I is an industrial interface converter that converts RS-232 signals into RS-422/RS-485 signals. It is used for integrating RS-232 devices into industrial networks that transmit data over longer distances, extending the transmission range from 15 meters with RS-232 to up to 1.2 km with RS-422/RS-485. The device is designed for use in critical industrial environments and provides robust and reliable interface conversion without requiring any changes to the existing hardware or software of connected devices.

Applications

The TCC-100I is used to integrate RS-232 devices such as measuring instruments, sensors, controls, or other industrial end devices into RS-422/RS-485 networks. These networks are typically found in automation systems, factory halls, power supply facilities, or machine building, where high immunity to interference and long transmission distances are required. The conversion enables the use of existing RS-232 technology in modern, more powerful network topologies.

Functions and Equipment in Detail

The converter supports conversion from RS-232 to RS-422 with RTS/CTS handshake, enabling bidirectional data transmission with transmission control. Additionally, conversion to RS-485 in both 2-wire and 4-wire topology is possible, allowing for both simple point-to-point and multi-point connections. LEDs for PWR (power supply), Tx (transmit), and Rx (receive) enable visual monitoring of the operating status. Wiring is done via a plug-in screw terminal block, ensuring a simple and secure connection for RS-422/RS-485 lines.

Technology Explained Simply

The TCC-100I offers 2 kV isolation protection for RS-422/RS-485 signals and for the power supply, ensuring galvanic isolation between the connected device and the network. This protects sensitive devices from voltage surges and potential differences. Additionally, an integrated ESD overvoltage protection of 16 kV safeguards the device against electrostatic discharges that may occur during handling or in industrial environments. The operating temperature ranges from -20 to 60 °C, enabling use in demanding climatic conditions.

Compatibility and Accessories

The converter is compatible with RS-232 devices and can be used in RS-422/RS-485 networks. Mounting is either on a wall or on a DIN rail, allowing flexible installation in enclosures or on walls. Wiring is done via the plug-in screw terminal block, designed for RS-422/RS-485 connections.

Mounting and Installation

Mounting is either on a DIN rail or on a wall, with device fixation via designated mounting points. Wiring of RS-422/RS-485 lines is done via the plug-in screw terminal block, enabling a secure and quick connection.

Advantages in Operation

Using the TCC-100I allows existing RS-232 devices to be used in modern RS-422/RS-485 networks, avoiding investment in new devices. Galvanic isolation and ESD protection increase the reliability and lifespan of the device in industrial environments. LED indicators simplify diagnosis and maintenance, while flexible mounting and easy wiring accelerate installation. The operating temperature range of -20 to 60 °C makes the device suitable for a wide range of applications, including outdoor areas or climatically demanding indoor spaces.
