Original Triconex 8312 power supply module for Tricon SIS chassis, hot‑swappable redundant power unit.

Product Overview

Triconex 8312 is a 230VAC input power supply module for Tricon SIS safety instrumented system. It converts AC input into multiple isolated DC outputs to power processor, communication and I/O modules inside the rack. It supports redundant parallel operation and hot‑swap function, widely used as maintenance spare part for ESD, HIPPS and burner management systems in petrochemical, oil‑gas and power plant.
