Core Technical Specifications & Product Specifications

Core Main Functions

4.1 Full-Rack Stable Power Distribution

As the core power source of the Tricon SIS system, the 2058 module undertakes centralized power conversion and stable power distribution for the entire system rack. It converts unstable industrial input power into high-precision regulated DC power, continuously and stably supplying power to main processors, communication modules, all I/O acquisition and output modules. It eliminates system operation abnormalities caused by industrial power grid fluctuation and ensures consistent and reliable power supply for all safety logic and signal acquisition links.

4.2 N+1 Redundant Parallel Hot Backup

The 2058 supports multi-module N+1 redundant parallel operation, realizing automatic load balancing and seamless hot backup between power units. When a single power module fails or is replaced, other backup modules automatically undertake the full rack load without power interruption, system reset or logic outage. This function completely avoids single-point power supply failures and greatly improves the overall availability of the SIS safety system.

4.3 Full-Link Power Fault Diagnosis & Protection

Integrating comprehensive power monitoring and protection circuits, the 2058 achieves full-coverage real-time diagnosis of over-voltage, under-voltage, over-current, short-circuit, over-temperature and abnormal load conditions. Once a fault is detected, the module triggers instantaneous self-protection, locks abnormal output, generates standard fault codes and uploads alarm information to the upper system. It effectively prevents module burnout, equipment damage and system failure caused by power anomalies.

4.4 Low-Noise & Isolated Anti-Interference Power Output

Adopting multi-stage filtering, isolation and ripple suppression technology, the 2058 outputs ultra-low-noise and low-ripple power. It isolates external power grid surge, electromagnetic interference and high-frequency clutter, preventing power noise from interfering with high-precision analog signal sampling and communication data transmission. It ensures signal accuracy and communication stability of the entire SIS system in complex industrial electromagnetic environments.

4.5 Zero-Downtime Online Maintenance & Continuous Operation

Consistent with Tricon series unified industrial design standards, the 2058 supports full online hot-swap function. Module replacement, power load testing, fault troubleshooting and power system parameter debugging can be completed during normal system and production operation. The maintenance process will not affect system power supply continuity and safety logic operation, realizing 24/7 uninterrupted stable operation of high-risk safety systems.
