Triconex RXM4201 Fiber Optic Remote Extender Module

Description

• Physical and Environmental Specifications
  • Its overall dimensions are 410 mm × 280 mm × 160 mm and weighs 6.8 kilograms, which is suitable for installation in standard industrial equipment cabinets.
  • The operating temperature range is -40°C to 70°C, and the storage temperature range is -40°C to 85°C, which can adapt to extreme temperature environments in both indoor and outdoor industrial sites.
  • It has an IP65 protection level and can work normally in an environment with a relative humidity of 10% to 95% without condensation, effectively resisting the erosion of dust and moisture.

Functional Characteristics

• Long-distance Stable Transmission and Anti-interference
  • The fiber optic communication method not only realizes the long-distance extension of the I/O bus but also avoids signal attenuation and interference that often occur in traditional cable transmission.
  • It provides ground loop isolation function, which can completely prevent equipment damage and signal distortion caused by ground loop problems in the industrial site, ensuring the accuracy of data transmission.
• Redundant Design and High Reliability
  • It adopts a redundant design that is compatible with the Triconex safety system. When a single module or a certain communication link fails, the standby mechanism can be activated immediately.
  • The module set composed of three identical modules can work together as a repeater, which further improves the stability of the system and ensures that the communication between the main control system and the remote I/O module will not be interrupted.
• Flexible Expansion and Convenient Maintenance
  • It supports expanding the I/O points of the system to 256 points. A primary module set can be connected to three remote module sets in the remote chassis, which meets the demand for multi-point and large-scale remote monitoring in industrial production.
  • It supports hot-swapping function. Maintenance personnel can replace the faulty module online without shutting down the entire control system, which greatly shortens the maintenance time and reduces production losses.

Application Scenarios

• Oil and Gas Industry
  • It is applied to offshore drilling platforms. It realizes long-distance data transmission between the central control room and the I/O modules of the drilling area and the oil and gas transmission area, and timely feeds back the signals of sensors such as gas concentration and pipeline pressure to the central control system to trigger emergency shutdown when an abnormality occurs.
  • It is used in onshore oil depots and long-distance oil and gas pipelines. It connects the remote I/O modules distributed along the pipeline with the main control center, realizing the centralized monitoring of the switch state of each valve and the operation state of the transfer pump.
• Chemical and Nuclear Industry
  • It is integrated into the safety control system of large chemical plants. It transmits the temperature, pressure and other process signals collected by the remote I/O modules of the reactor area and the storage area to the central control room, ensuring the safe progress of chemical reactions.
  • It is used in the safety system of nuclear power plants. It realizes the long-distance communication between the main control system and the I/O modules of the cooling system and the radiation detection area, ensuring the real-time monitoring of key equipment and the timely transmission of safety signals.
• Power and Transportation Industry
  • It is deployed in thermal power plants and hydropower stations. It connects the I/O modules of the power generation unit area, the transformer area and other remote areas with the central control system, ensuring the stable operation of the power generation process and the reliable transmission of equipment operation data.
  • It is applied to railway and urban rail transit control systems. It realizes long-distance data interaction between the central dispatch system and the I/O modules of each station and section, supporting the real-time monitoring of train operation status and the transmission of scheduling signals.
• General Industrial Automation
  • It is used in large-scale metallurgical factories. It connects the I/O modules of blast furnace, converter and other production areas with the central control center, which is convenient for the centralized control of the metallurgical process and the timely handling of abnormal conditions.
  • It is integrated into the automatic control system of large-scale water treatment plants. It transmits the water quality detection signals and equipment operation signals collected by the remote I/O modules of each treatment unit to the main control system to ensure the stability of the water treatment process and the compliance of the effluent quality.
