TRICONEX 8310N2 Power Supply Module

Product Description

The Triconex 8310N2 is a high-reliability, fault-tolerant Power Supply Module engineered by Schneider Electric for the Tricon V10 Safety Instrumented System (SIS) chassis. This dual-input card converts 120VAC or 120VDC source lines into a stabilized 6.5VDC backbone feed, delivering continuous 175W power up to 60°C to guarantee critical process safety.

Industrial Application Scenarios

The TRICONEX 8310N2 power module is deployed within heavy industrial control cabinets managing high-risk safety-instrumented functions in oil and gas refineries, chemical manufacturing complexes, large nuclear and thermal power utilities, and automated CNC production floors. Inside the main Tricon chassis, these power units operate in redundant pairs. If one utility grid leg fails or an upstream substation branch short-circuits, the 8310N2 utilizes its extended input voltage range and hold-up time to ride through the power disturbance. This keeps the safety processors fully energized and prevents unnecessary plant-wide emergency shutdowns.
