Description

PS01-B: Product Overview
The ICS Triplex PS01-B is a triple modular redundant power supply module designed for high-availability safety instrumented systems. This module functions as the primary power conversion unit within the Trusted system platform, providing reliable DC-DC power conversion with built-in redundancy for critical control applications. The power supply operates as part of a fault-tolerant architecture where three independent power conversion channels work in parallel to ensure continuous system operation even in the event of a single or multiple component failures.
Installed in a Trusted system chassis, the module accepts 24V DC input power and converts it to the 5V DC required by the system’s logic circuits and I/O modules. The triple redundant design incorporates three independent power conversion circuits that operate in parallel, with voting logic that continuously monitors the output of each channel. If one channel fails or drifts outside acceptable parameters, the remaining channels continue to provide stable power while the system alerts operators to the condition. This architecture maintains power integrity without interruption, supporting the overall safety integrity level (SIL) requirements of the system.
As a critical component of the Trusted safety platform, this power supply module supports hot-swap capability, allowing for maintenance or replacement without shutting down the entire safety system. The module includes comprehensive status monitoring and fault reporting capabilities that integrate with the chassis management system. The design emphasizes fault tolerance and diagnostics, providing early warning of potential issues before they can affect system availability. The robust construction and redundant architecture make this power supply suitable for demanding industrial environments where power quality and availability are critical to safety system performance.

Core Features & Customer Value
Triple Modular Redundant Architecture: The triple redundant power conversion design ensures continuous operation even with multiple component failures. Three independent power channels operate in parallel with continuous monitoring and voting logic. For safety system applications, this redundancy provides the fault tolerance necessary to maintain system availability while meeting safety integrity level requirements. The design prevents single points of failure in the power supply path, which is critical for safety instrumented systems where power loss could compromise the safety function.
Hot-Swap Capability: The module can be inserted or removed from a powered chassis without disrupting system operation. This capability allows for maintenance and replacement activities without requiring a system shutdown. For continuous process operations, this feature significantly reduces maintenance downtime and allows for proactive replacement of modules showing early signs of degradation. The hot-swap design includes controlled power sequencing and arc suppression to ensure safe insertion and removal under load.
Comprehensive Diagnostics and Monitoring: Continuous monitoring of all power supply parameters provides early detection of potential failures before they affect system operation. The module reports voltage, current, temperature, and redundancy status to the chassis management system. This diagnostic capability enables predictive maintenance strategies and provides operators with advanced warning of developing issues. The comprehensive monitoring supports the overall safety case for the system by demonstrating continuous compliance with performance requirements.
Typical Applications
In emergency shutdown systems for oil and gas production facilities, the power supply provides reliable power to the safety controllers that monitor critical process parameters and execute shutdown commands. The redundant architecture ensures that power is maintained even if individual components fail, supporting the high availability requirements of safety systems in continuous process operations.
For fire and gas detection systems in petrochemical plants, the module powers the logic solvers that process signals from gas detectors and flame detectors. The hot-swap capability allows for maintenance activities without disabling the entire safety system, maintaining protection while individual modules are serviced or replaced.
In turbine control systems, the power supply provides clean, stable power to the triple modular redundant controllers that manage critical speeds and temperatures. The wide operating temperature range ensures reliable operation in the harsh environments typical of turbine enclosures and compressor stations.
