TRICONEX 8312 Rack-mounted AC Power Module

I. Product Positioning
This 230VAC input rack power supply is compatible with the Tricon 3000 (8110 chassis) SIS safety system and provides unified power supply for the chassis backplane, CPU, I/O, and communication cards; it is standardly configured for dual redundant parallel use, eliminating single-point power failures, meeting SIL3 safety level requirements, and supporting online hot-swappable replacement.
Different power supplies in the same series
8312: High-power 230VAC (187~253VAC, 47–63Hz) power supply, mainstream field standard configuration
8311: 115VAC low-voltage input version, used in some foreign factory areas

Electrical Input and Output Specifications
AC Input
Rated 230VAC, input range 187~253VAC, built-in 2.5A delay fuse
Three isolated DC outputs (with short circuit / overvoltage protection)
5VDC logic power: 20A, supplies CPU, backplane bus, card digital circuits
24VDC field I/O power: 8A, supplies DI/DO/AI/AO card circuits
24VDC auxiliary power: 1A, used for fans, alarm circuits
Total output power of the entire machine ≈ 432W. Modules are parallel-connected for automatic current sharing, and if one module fails, the other module will carry the full load.s.

Key Technical Parameters
Working Voltage: DC 24V
Contact Rated Current: 10A
Electrical Isolation Grade: 2500V RMS
Installation Method: Tricon Standard Rack Slot Installation
Function: On-site Terminal + Relay Electrical Dual Isolation

Application Scenarios
Used in SIS safety instrument systems and ESD emergency stop systems in industries such as petroleum, chemical, and power, in conjunction with Triconex relay output cards, to achieve electrical isolation protection between the strong electrical circuits on site and the weak electrical side of the safety control system.
