Description
Key Technical Specifications
- Output and Redundancy Performance: The module is equipped with 40 output channels, which are divided into 5 power groups, with 8 channels in each group. It adopts a TMR architecture, which realizes triple redundancy inside the module. Even if a single channel fails, the system can still maintain continuous operation through redundant mechanisms, avoiding data loss and system downtime. It can generate precise analog signals to control on-site actuators and process equipment, ensuring the accuracy of industrial process control.
- Safety and Monitoring Capabilities: It has a 2500V electrical isolation barrier, which can effectively isolate electrical interference between circuits, ensuring the safety of electrical use and the stability of signal transmission in complex industrial environments. It is also equipped with comprehensive automatic diagnosis and line monitoring functions, which can detect open and short circuit faults of load equipment in a timely manner. The front-panel LED indicators can display the real-time status and fault information of each channel, facilitating maintenance personnel to quickly locate problems. In addition, the overcurrent protection function can quickly respond when an overcurrent fault occurs in the circuit to avoid module and load equipment damage.
- Power Supply and Physical Characteristics: Its working voltage ranges from 20VDC to 32VDC, the system power consumption is 22W, and the field power consumption can reach 28W when the channel current is maximum. The weight of the module is about 1kg, which is easy to install and integrate into the existing Trusted TMR system. It supports online hot-swapping. Through matching slots or intelligent slot configuration, it can be replaced without interrupting the system operation, greatly improving the maintenance efficiency.

Field Application & Problem Solved
- Oil and Gas Drilling Process Control: In oil and gas drilling operations, multiple actuators such as valves and pumps need stable analog signals to control their opening and closing degrees and operating speeds. The T8480 module can provide continuous and precise analog output for these actuators. Its TMR architecture and fault detection function can avoid system failures caused by signal interruption due to module faults. When a channel malfunctions, the redundant mechanism is activated immediately, ensuring the normal progress of drilling operations and reducing the risk of economic losses caused by operational suspension.
- Nuclear Power Plant Safety System Control: Nuclear power plants have extremely high requirements for the reliability of control systems. The T8480 module can be used in the safety monitoring and control system of nuclear power plants to output analog signals for equipment such as temperature and pressure control components. Its 2500V high isolation performance can resist strong electromagnetic interference in the nuclear power plant environment, and the automatic diagnosis function can timely detect circuit faults. Meanwhile, the hot-swapping feature allows maintenance personnel to replace the module without shutting down the key system, avoiding potential safety hazards caused by long-term system shutdown.

Installation & Maintenance Pitfalls (Expert Tips)
- Hot-Swapping Operation Specifications: Although the module supports hot-swapping, it is necessary to strictly follow the operation procedures during replacement. It is necessary to confirm that the system is in a stable redundant operation state first, and wear anti-static gloves during the operation to prevent static electricity from damaging the module’s internal components and avoid short circuits caused by incorrect plugging and unplugging.
- Grouped Wiring Notes: The 40 channels of the module are divided into 5 power groups. When wiring, the lines of different groups should be laid separately. Do not mix them randomly, so as to prevent mutual interference between groups and ensure the independence and stability of each channel’s signal transmission. In addition, keep the connecting lines away from high-voltage cables to avoid the isolation effect being affected by electromagnetic interference.
- Regular Indicator and Fault Checks: During daily maintenance, pay close attention to the status of the front-panel LED indicators. If an abnormal indicator is found, immediately check the corresponding channel, circuit and load equipment. At the same time, regularly test the automatic diagnosis function of the module to ensure that it can normally detect open circuits, short circuits and overcurrent faults, so as to avoid potential safety hazards caused by delayed fault discovery.
