Description

T7150A: Product Overview

The ICS Triplex T7150A is a DC Power Supply Module engineered for the Trusted Triple Modular Redundant (TMR) safety instrumented system. This module serves as the primary power source for the system’s main or expansion chassis, converting facility AC power to the regulated DC voltages required by the controller, communication, and I/O modules. Its design is critical to achieving the overall system’s high availability and fault tolerance.

Within the Trusted system architecture, this power supply occupies a dedicated slot in the chassis. Its fundamental role is to ensure clean, stable, and continuous power distribution to all modules within the rack, even during fluctuations in the input AC source. The module incorporates power conditioning circuitry to protect downstream components from electrical noise, spikes, and sags. It provides comprehensive monitoring of its own status, including input voltage presence, output voltage regulation, temperature, and load current, reporting this information to the system controller for health monitoring.

As a core component of the Trusted TMR platform, the T7150A is designed to be deployed in a redundant N+1 configuration. This means that a chassis can be populated with multiple power supplies, where the total capacity of (N) modules is sufficient to power the entire chassis, and the (+1) additional module provides redundancy. If one power supply were to fail, the remaining units automatically and seamlessly share the load without any interruption to the control system. This hot-standby capability is a cornerstone of the platform’s high availability, ensuring that a single point of failure in the power system does not lead to a process shutdown.

Core Features & Customer Value

N+1 Redundant Configuration and Hot-Swap Capability: The ability to install multiple power supplies in a load-sharing, redundant configuration is the primary value of this module. For the control engineer, this design eliminates the power supply as a single point of failure. The hot-swappable feature allows a faulty unit to be replaced while the system remains online, which is critical for processes where unscheduled downtime results in significant production or safety impacts. This translates directly to higher overall system availability and a reduction in mean time to repair (MTTR).

Comprehensive Diagnostics and Protections: The module continuously monitors its health and performance, providing status information to the system controller. This allows for predictive maintenance, as trends in performance can be monitored, and faults can be announced before they lead to a supply failure. The suite of internal protections (overvoltage, overcurrent, overtemperature) safeguards not only the power supply itself but also the valuable controller and I/O modules in the chassis from electrical damage. This protection reduces the risk of collateral damage during abnormal electrical events, minimizing repair costs and downtime.

High Efficiency and Thermal Management: With an efficiency rating exceeding 85%, the power supply generates less waste heat, which reduces the thermal load on the control panel. This improved thermal performance enhances the long-term reliability of all components within the enclosure. The integrated, controlled-speed cooling fan ensures adequate airflow while minimizing acoustic noise and dust accumulation. For the system designer, this high efficiency can allow for the specification of smaller enclosures or less aggressive panel air conditioning, resulting in lower overall system costs.

Typical Applications

The T7150A is deployed wherever a highly available Trusted TMR system is required. In offshore oil and gas platforms, this power supply is used within the Emergency Shutdown System (ESD) and Fire and Gas (F&G) system panels. The N+1 redundancy ensures that a single power supply failure, perhaps due to the harsh, corrosive environment, does not compromise the platform’s primary safety systems, preventing catastrophic events and ensuring personnel safety.

In critical compressor stations along natural gas pipelines, the power supply provides reliable power to the turbine control and compressor anti-surge systems. The stability of the DC power is crucial for the accurate operation of analog I/O modules controlling fuel valves and recycle valves. The power supply’s immunity to input voltage fluctuations ensures consistent operation despite potential voltage sags or spikes common in remote utility power supplies.

For burner management systems (BMS) on large industrial boilers in power generation or chemical plants, the continuous operation of the safety controller is non-negotiable. The redundant T7150A configuration guarantees that the logic solvers monitoring flame status, fuel pressure, and air flow remain powered, ensuring safe start-up, operation, and shutdown sequences are always executed correctly, thus preventing furnace explosions.
