Key Features & Benefits
High‑Reliability Redundant Design
Supports N+1 and full redundancy. Multiple shelves can be cascaded to expand capacity and redundancy. Power modules operate with load sharing; single‑point failure does not affect system power supply, meeting high‑availability requirements of SIL 3 safety systems.
Hot‑Swap & Easy Maintenance
Power modules support online hot‑swap for maintenance without shutdown. The shelf is equipped with a Power Port for real‑time input/output status monitoring, and relays overvoltage, overtemperature, fan failure and other alarms via relay contacts.
Flexible Configuration & Expansion
Can work with an optional rack‑mount power controller for real‑time output voltage/current configuration, monitoring up to 4 shelves and 12 power modules. Supports current sharing, current limiting, and power factor correction to match various load demands.
Industrial‑Grade Protection & Compliance
Compliant with CISPR22 Class B, EN 55022 Class B EMC standards with strong immunity. Certified by UL and CE, suitable for high‑safety industries such as petrochemical, power generation, and rail transit.
3. Installation & Maintenance Guidelines
Installation
Mounted in a 19‑inch standard rack, 1U height saves cabinet space; supports stacking up to 4U.
Power modules are connected via latch connectors for secure installation. Unused slots must be fitted with T8235 blanking plates to ensure cooling and protection.
The Power Port is installed at the rear of the shelf for diagnostics and controller connection. Addresses are set via jumpers to avoid conflicts between multiple shelves.Maintenance
In case of power module failure, replace directly by hot‑swap. AC OK and PWR OK LEDs indicate status (green = normal, amber = fault).Regularly check fan operation; use Power Port alarm signals to troubleshoot overtemperature and fan faults. Clean the shelf interior to maintain cooling efficiency.For multi‑shelf cascading, use TC‑323 interconnection cables to ensure proper current sharing and monitoring. Secure unused connectors to avoid interference.
Companion Products
- Power Modules: T8231 (24VDC, 750W), T8232 (28VDC adjustable, 750W), providing main power for the shelf.
- Accessories: T8235 blanking plate (covers empty slots), TC‑323 interconnection cable (shelf cascading), rack‑mount power controller (central monitoring and configuration).
- Trusted Control System: Used with Trusted series controllers (e.g., T8100 main chassis, T8431 expansion processor), I/O modules and communication modules to build a complete triple‑modular redundant safety control system.
