The Moxa TCF-142-S-ST-RM is a plug-in module for the NRack system, specifically designed for integration into the housing TRC-190. It serves as a serial-to-fiber optic converter and enables the transmission of serial data into a fiber optic signal. The conversion is performed for serial interfaces RS-232, RS-422, and RS-485, thereby enabling the connection of legacy systems to modern fiber optic networks. The module is designed for use in industrial environments where reliable and interference-resistant data transmission over long distances is required.

Applications

The TCF-142-S-ST-RM is used in industrial networks, particularly in scenarios where existing serial devices such as sensors, controls, or measuring instruments are to be connected to a network via fiber optic. It is suitable for installations in the manufacturing industry, energy supply, transportation technology, and other fields where high interference resistance and long transmission distances are necessary. The use in the TRC-190 housing enables modular expansion of rack systems without additional space requirements.

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, enabling data transmission via fiber optic cables. This ensures high data integrity and interference resistance against electromagnetic influences. The serial interfaces are designed for operation in industrial environments and support various data rates and configurations. The fiber optic side of the module is designed for single-mode fibers, enabling transmission over longer distances. The conversion is bidirectional, allowing data to be transmitted in both directions.

Technology Explained Simply

The technology of the TCF-142-S-ST-RM is based on converting electrical serial signals into optical signals, which are transmitted via fiber optic cables. This is achieved through an integrated converter that transforms electrical pulses into light pulses and vice versa. The use of single-mode fiber enables transmission over greater distances with minimal signal attenuation. The serial interfaces RS-232, RS-422, and RS-485 are widely used in industry and allow the connection of various devices. The conversion occurs without additional power supply for the module, as it is integrated into the TRC-190 housing and depends on its power supply.

Compatibility and Accessories

The module is specifically developed for the TRC-190 housing and can only be used in this system. It is compatible with single-mode fiber optic cables and supports the serial interfaces RS-232, RS-422, and RS-485. The connection is made via a standard connector on the serial side and an ST connector on the fiber optic side. No additional adapters or converters are required for integration into existing systems, as the interfaces are standardized. The use in a rack system enables modular expansion without additional hardware.

Mounting and Installation

Installation is performed by inserting the module into the TRC-190 housing. No tools are required, as the module is mechanically inserted into the housing. The electrical connection is made via the integrated power supply of the TRC-190. The serial interface is connected to the device to be connected via an appropriate cable. On the fiber optic side, an ST connector is attached to the fiber optic cable. Installation requires no additional configuration, as the module is standardly configured for the mentioned protocols.

Advantages in Operation

The use of the TCF-142-S-ST-RM provides reliable and interference-resistant data transmission, especially in environments with high electromagnetic interference levels. The use of fiber optic enables transmission over long distances without signal loss. The modular design in the TRC-190 housing simplifies integration into existing systems and allows flexible expansion. Compatibility with common serial protocols RS-232, RS-422, and RS-485 ensures the connection of various devices without additional modifications.
