TRICONEX 3625C1 Redundant Power Supply Module
Product Overview
The TRICONEX 3625C1 is a high-reliability redundant power supply module designed for TRICONEX’s Tricon safety instrumented system (SIS), a critical platform for industrial safety and control. It serves as the primary power source for the Tricon system, converting incoming AC power into stable 24V DC power to supply critical components like CPUs, input/output modules, and communication interfaces. This functionality is essential for maintaining continuous operation in high-risk industrial environments where power interruptions could lead to safety incidents.
The TRICONEX 3625C1 features a redundant design with dual power paths, ensuring that if one path fails, the other automatically takes over without interrupting power. It supports a wide input voltage range, making it compatible with global power grids, and includes built-in protection mechanisms such as overvoltage, overcurrent, and short-circuit safeguards. These features protect connected modules from electrical faults, enhancing system durability.
As part of the Tricon ecosystem, the TRICONEX 3625C1 integrates seamlessly with components like the TRICONEX 3503E (CPU module), TRICONEX 3511 (digital input module), and TRICONEX 8312 (rack assembly). It operates in temperatures from 0°C to 60°C, resists dust, vibrations, and humidity, and is certified for use in hazardous areas (ATEX, IECEx). Its compact design fits into standard Tricon racks, while LED indicators for power status and faults simplify monitoring.
Whether used in oil refineries, chemical plants, or nuclear facilities, the TRICONEX 3625C1 ensures uninterrupted power to safety-critical systems, forming the backbone of reliable automation infrastructure.

Main features and advantages
Redundant design: The 3625C1 uses two independent power paths. If one path fails, the other switches on instantly, ensuring no power interruption. This eliminates single points of failure, meeting SIL 3 requirements critical for applications like oil refinery emergency shutdown systems, where power loss could cause catastrophic leaks.
Wide input compatibility: It accepts 85–264V AC input, working with global power grids without needing voltage converters. This simplifies installation in international facilities, from European factories (230V AC) to North American plants (120V AC).
Comprehensive protection: Built-in overvoltage, overcurrent, and short-circuit safeguards prevent damage to the 3625C1 and connected modules. For example, a short in a field device triggers the module to cut power temporarily, protecting the CPU and I/O modules from electrical damage.
Industrial ruggedness: The 3625C1 operates in temperatures from 0°C to 60°C and resists dust, vibrations, and humidity. It performs reliably in harsh settings—from freezing LNG terminals to humid offshore platforms—reducing unplanned downtime.
Easy integration: The module fits directly into Tricon racks like the 8312, connecting to the backplane to distribute power. It requires no external wiring beyond AC input, simplifying installation in both new systems and retrofits.
Clear status monitoring: LED indicators show power status for each redundant path and fault alerts. This allows technicians to quickly identify issues like a failed power path, speeding up troubleshooting during maintenance.

Installation and maintenance
Pre-installation preparations: Power off the Tricon rack (e.g., 8312) before installing the 3625C1. Verify that the AC input supply matches the 85–264V AC range. Inspect the module for physical damage, ensuring connectors are clean and intact. Use an anti-static wristband to handle the module, as static discharge can damage internal components. Align the module with the rack’s guide rails and secure it with M6 screws.
Maintenance suggestions: Inspect the 3625C1 quarterly. Check AC input connections for tightness and wipe dust from the module’s surface with a dry cloth. Monitor LED indicators to ensure both power paths show normal operation—flashing or off LEDs may indicate a path failure. Test output voltage annually using a multimeter to verify it stays within 24V DC ±5%. Replace the 3625C1 if faults persist after checking input power, following proper shutdown procedures to avoid disrupting the Tricon SIS.
Application fields
The TRICONEX 3625C1 is widely used in high-risk industries requiring uninterrupted power for safety systems:
In oil and gas production, it powers emergency shutdown (ESD) systems on offshore platforms. The 3625C1 ensures the Tricon CPU and 3700 output modules receive continuous power, allowing rapid valve closures if gas leaks are detected via 3511 input modules.
In chemical processing, the 3625C1 supplies power to reactor safety systems. It maintains power to temperature sensors (connected to analog input modules) and shutdown relays, ensuring the system can halt reactions if pressure exceeds safe limits.
In nuclear power plants, it powers radiation monitoring and coolant control systems. The module’s redundancy ensures power to critical components, supporting rapid response to abnormal conditions to prevent core damage.
In pharmaceutical manufacturing, the 3625C1 powers clean room safety interlocks. It keeps door sensors and alarm systems operational, maintaining sterile conditions and compliance with regulatory standards.
