General
Fibre optic connector	SC

The Moxa TCF-142-S-SC-RM is a plug-in module for the NRack system, specifically designed for integration into the TRC-190 enclosure. It serves as a serial-to-fiber optic converter, enabling the transmission of serial data, which is transmitted via RS-232, RS-422, or RS-485, into a fiber optic signal. This conversion is particularly necessary in industrial environments where high data integrity, long transmission distances, and immunity to electromagnetic interference are required. The module is part of the TCF-142-RM series and is used in rack systems to connect existing serial devices with modern fiber optic networks.

Applications

The TCF-142-S-SC-RM is designed for industrial applications where serial communication over long distances is required, for example in automation technology, power supply, or transportation infrastructure. It is suitable for connecting sensors, controls, measuring devices, or other serial end devices to a fiber optic backbone. The use in a rack system enables a structured and space-saving installation in server or network room environments.

Functions and Equipment in Detail

The module converts serial signals of the protocols RS-232, RS-422, and RS-485 into a fiber optic signal. This conversion is bidirectional, allowing data to be transmitted in both directions. The support of multiple serial interface formats enables flexible connection of various devices. Fiber optic transmission offers higher immunity to interference compared to conventional copper cables, lower signal loss over long distances, and no galvanic connection, which increases safety in electrically hazardous environments.

Technology Explained Simply

The conversion is performed by an integrated transceiver, which converts the electrical serial signal into an optical signal and vice versa. The use of single-mode fiber optic enables transmission distances of several kilometers, depending on the network configuration. The SC (Subscriber Connector) interface is a standard for fiber optic connections and ensures a secure and mechanically stable connection. The plug-in module form for the TRC-190 enclosure allows modular expansion of the rack system without additional mounting work.

Compatibility and Accessories

The module is specifically developed for the TRC-190 enclosure and requires this enclosure for installation. It is part of the TCF-142-RM series and can be combined with other modules of this series in a rack system. Compatibility with serial devices supporting RS-232, RS-485, or RS-422 is given.

Mounting and Installation

Installation is performed by inserting the module into the TRC-190 enclosure. Mechanical fixation is achieved via integrated holders in the enclosure. The electrical connection is made via the serial interface on the module, which is connected to the device to be connected. Fiber optic cables are connected to the SC interface of the module. Configuration is done via the serial interface, where the exact parameters (baud rate, parity, data bits) must be adjusted to the requirements of the connected device.

Advantages in Operation

Using the TCF-142-S-SC-RM enables reliable and interference-resistant data transmission over long distances. The galvanic isolation provided by fiber optic transmission protects connected devices from voltage surges and grounding differences. The modular design in the rack system simplifies maintenance and expansion of the infrastructure. Support for multiple serial protocols increases flexibility when integrating devices.
