T3401: Product OverviewThe T3401 is a critical infrastructure component within the ICS Triplex Trident and Trusted safety instrumented system (SIS) architectures. Its designated role is to serve as the primary power conversion unit for a system chassis. By accepting a universal AC mains input, it generates and regulates the multiple DC voltage levels required by the various processor, communication, and I/O modules residing in the rack. Without a stable and reliable power source from the T3401, the entire safety function of the rack would be inoperative. The module is designed to be mounted in a dedicated slot, typically in a chassis that can accommodate multiple power supplies for redundancy.The core functionality involves the conversion of incoming AC voltage, which can vary widely depending on geographic location (e.g., 110 VAC or 220 VAC), into precise, low-noise DC outputs. These outputs, commonly 5 VDC for the core logic and 24 VDC for I/O modules and auxiliary circuits, are delivered to the chassis backplane. The backplane then distributes this power to all other modules. The T3401 incorporates filtering and regulation circuitry to protect the sensitive electronics of the SIS from voltage sags, surges, and electrical noise present in an industrial environment. It belongs to the Trident and Trusted product families, which are defined by their commitment to fault tolerance and adherence to international safety standards like IEC 61508. The benefit of integrating the T3401 into this platform is a cohesive system where power, logic, and I/O are engineered to work together, with built-in diagnostics that enhance overall system integrity and simplify validation efforts.

Core Features & Customer ValueUniversal AC Input Range: The module accepts a wide input voltage range from 90 to 264 VAC at 47-63 Hz. This flexibility allows the same hardware to be used in diverse geographical locations without modification, simplifying procurement, sparing, and deployment logistics for multinational corporations.Dual Isolated Outputs: It provides two independently regulated DC outputs, typically 5 VDC and 24 VDC. This separation is crucial for maintaining signal integrity; it isolates the sensitive processor logic from the potentially noisy power demands of field I/O, thereby reducing the risk of erratic behavior caused by electrical interference.Comprehensive Protection Mechanisms: The T3401 includes electronic protection against overvoltage, overcurrent, and short circuits. For the end user, this means enhanced safety for the connected modules and a reduced likelihood of catastrophic failure due to electrical anomalies, which translates to greater system uptime.Integrated Health Monitoring: The module continuously monitors its own operational status, including output voltage levels and internal temperature. This data is made available to the system controller, allowing operators to anticipate potential failures and schedule maintenance proactively, rather than reacting to an unexpected outage.Robust Mechanical Design: Housed in a metal enclosure that meets industrial standards, the T3401 is built to withstand the vibrational and thermal stresses of a plant environment. This durability ensures a long service life and reliable performance under challenging conditions.

Typical ApplicationsThe T3401 is fundamental to any application employing the ICS Triplex Trident or Trusted systems. In an offshore oil platform’s emergency shutdown (ESD) system, it would power the safety controller rack responsible for isolating the wellheads and activating blowdown valves in case of a hydrocarbon leak. The module’s ability to handle wide input voltage fluctuations is particularly valuable in such remote locations where power quality can be inconsistent.In a large-scale chemical plant, the T3401 provides power to the safety system that protects a catalytic cracking unit. Here, it must operate reliably amidst high electromagnetic interference from large motors and variable frequency drives. The power supply’s filtering capabilities are essential to maintain the integrity of the safety logic.For a power generation facility, the module is used to power the burner management system (BMS) controller. In this role, it ensures that the safety functions governing the ignition and shutdown of gas turbines have an uninterrupted power source, contributing to both efficiency and safety. The common thread across these applications is the need for a dependable power foundation for critical safety functions.
