TRICONEX 8120E Redundant Control System Framework
The TRICONEX 8120E is a core component of the Triconex series safety instrumented systems under Schneider Electric. It is a redundant control system framework based on Triple Modular Redundancy (TMR) architecture. Below is its comprehensive detailed information:
The TRICONEX 8120E integrates three isolated, parallel control systems and independent diagnostic circuits into one system. It provides highly reliable, error-free, and uninterrupted process control through a 2-out-of-3 voting mechanism, ensuring the system does not fail due to single-point faults.
- Input Voltage: 24V DC or 100-240V AC
- Output Voltage: 5V DC
- Operating Temperature Range: -40°C to 70°C
- Storage Temperature Range: -50°C to 85°C
- Dimensions: 150mm × 110mm × 80mm
- Weight: 1.5kg
- Processor: 32-bit PowerPC 603e with a clock speed of 400MHz
- Memory: 256MB
- Storage Space: 2GB
Supports Modbus, Ethernet, RS232, RS485, etc.
Each module is equipped with independent processors and memory, making decisions through voting mechanisms to ensure high system availability. This redundant design significantly enhances reliability—even if one module fails, the system can still operate normally.
The system adopts a modular design, supporting various module types including digital input modules, digital output modules, communication modules, and safety modules. This facilitates expansion and maintenance, allowing users to add or replace modules according to actual needs to meet different control requirements.
The company has multiple main brands, and if you have other brand requirements, you can also send them to customer service for inquiry.
