TRICONEX 8307A Expansion/RXM Rack Power Supply Module (230VAC Input, 24VDC Output) for Tricon SIL 3 SIS

Product Description

The TRICONEX 8307A is a hot-swappable redundant power supply module engineered by TRICONEX (Schneider Electric, former Invensys) for Expansion/RXM remote racks in Tricon/Tricon CX SIL 3 safety instrumented systems (SIS). Designed as a critical power conversion and distribution component for distributed I/O chassis (e.g., 8101, 8112), this module converts 230VAC input to regulated 24VDC output to power TMR I/O modules, backplane circuits, and communication components—with overvoltage/overcurrent protection, thermal shutdown, and hardwired alarm contacts for fault notification. It supports redundant (N+1) deployment, hot-swap maintenance, and seamless integration with Tricon expansion/RXM racks—making it ideal for distributed emergency shutdown (ESD), fire & gas (F&G), and process safety systems in oil & gas, chemical, petrochemical, and power generation industries.

Key Functions

The 8307A power supply module delivers reliable, redundant power for remote expansion/RXM racks in safety-critical applications. Key functions include: 230VAC input (2A rating) to regulated 24VDC output; per-module overvoltage, overcurrent, and thermal protection to prevent damage to I/O modules and backplane; hardwired NO/NC alarm contacts for remote fault monitoring (rated 125VAC 1A); hot-swappable design for online maintenance without system shutdown; redundant (N+1) configuration support to maximize uptime; LED status indicators for input power, output voltage, module health, and alarm activation; and compliance with IEC 61508 SIL 3, FM, CSA, ATEX, IECEx standards—ensuring reliable operation in harsh industrial environments.

Application Scenarios

The TRICONEX 8307A power supply module is deployed in safety-critical industrial applications requiring redundant, regulated power for distributed Expansion/RXM racks. In offshore oil & gas platforms, it powers remote I/O modules for wellhead ESD valves and subsea sensor arrays connected via fiber optics. For chemical and petrochemical plants, it supplies power to remote process units, storage tanks, and toxic gas detection zones—supporting coordinated safety shutdowns. In power generation facilities, it is used for turbine hall, boiler house, and switchyard remote I/O racks, enabling real-time monitoring and control of critical safety equipment. The module is also suitable for mining, pharmaceutical, and water/wastewater treatment—all scenarios where high-availability power for distributed SIS is mandatory.
