The Triconex 8312 Power Supply Module provides essential logic power to modules in the Main, Expansion, or RXM Chassis. Available in 24 VDC, 115 VAC, and 230 VAC versions, it delivers 175 W at 60°C, ensuring stable operation even in challenging industrial environments. Each chassis contains two power modules for redundancy. This design allows either module to handle the full load independently.
You can replace modules online without interrupting system operation. Terminal strips for grounding, incoming power, and alarm connections are located conveniently at the lower-left corner of the backplane, simplifying maintenance.
Key Features
- Redundant power supply ensures continuous operation even if one module fails.
- Provides 175 W output and up to 27 A at 60°C.
- Maintains stable 6.5 VDC output with ±1% tolerance.
- Supports online replacement without downtime.
- Includes alarm contacts for missing modules, system faults, low battery, over-temperature, and configuration conflicts.
- For ATEX hazardous locations with 230 VAC, use the 8311 24 VDC module for compliance.
