Description
- Functional Features
- Triple Modular Redundancy for High Reliability
The module adopts triple modular redundancy technology. When a single module has a fault, the other two normal modules can still ensure the continuous and stable operation of the input function. This redundant design avoids system downtime caused by single-point faults, which is in line with the high safety requirements of industrial safety instrumented systems and greatly improves the overall availability of the control system.
- Independent Isolation to Resist Interference
Each of its 32 input points adopts a non-shared and independent isolation design. The high isolation voltage can isolate the electrical signals of each channel from each other. It can effectively prevent electromagnetic interference and voltage fluctuation from affecting signal transmission in complex industrial electrical environments, ensuring the accuracy and stability of input signals, and avoiding misoperation of the control system caused by signal distortion.
- Comprehensive Diagnostic and Status Monitoring
It is configured with perfect diagnostic indicator functions. Each input point is equipped with an independent status indicator, and the module itself has indicators for pass, fault and active states. Operators can directly observe the working status of each input channel and the overall operation of the module through these indicators. This real-time monitoring function enables timely discovery of signal transmission faults or module malfunctions, which is convenient for rapid troubleshooting.
- Flexible Matching and Easy Installation
It supports matching with unified and non-unified terminal panels, which can meet different wiring and installation needs on site. The modular structural design is consistent with the overall design style of Triconex series modules. It can be quickly installed on the corresponding baseplate of the control system, and can be flexibly combined with other Triconex modules to form a complete control system, reducing the difficulty of system configuration and installation.
