Triconex 8312 Power Module

Product Description

Triconex 8312 is a 230VAC power supply module dedicated for Tricon Triple Modular Redundant (TMR) safety systems, belonging to Invensys Triconex (now Schneider Electric) safety instrument system. It converts 230V AC input into regulated DC power for the system backplane. Hot-swap is supported and it is normally deployed in redundant pairs. Built-in fault diagnostics, status LED indicators and time-delay fuse protection are included. It features 20 ms hold-up time to withstand momentary voltage dips, ensuring continuous operation of SIS/ESD safety systems and meeting SIL3 safety integrity requirements.
