Basic Information
Brand:ICS Triplex
Model:T9451
Product Type:Digital Output Module
Number of Output Channels:8
Operating Voltage:Typically 24VDC,with some models supporting 24/48VCC
Weight:Approximately 340g
Technical Specifications
Output Current:Each channel can safely and reliably drive up to 1A at 32VDC.
Isolation:Optocoupler isolation.
Response Time:Microseconds.
Operating Temperature Range:-40°C to+85°C.
Mounting Method:Rack-mountable within the ICS Triplex AADvance system.Features
High Fault Tolerance:Utilizing a Triple Modular Redundant(TMR)architecture,each output channel within the module consists of three independent modules.A voting mechanism achieves high reliability,enabling detection and tolerance of individual module failures.Even if two internal channels fail,output accuracy and reliability are guaranteed.
Comprehensive Output Protection:Each output channel features voltage and load current monitoring,reverse current protection,and short-circuit and open-circuit monitoring,effectively protecting the module and connected field devices.
Flexible Control Modes:Supports multiple control modes,including latching,pulse,and analog,to adapt to diverse application requirements and control strategies.
Support for dual redundant power supplies:Further enhancing power supply reliability,ensuring continued operation even if one power supply fails.
Output Channel Isolation:Each output channel is electrically isolated from the others,as well as from the module’s internal circuitry,effectively preventing cross-channel interference and fault propagation.
Applications:Safety Instrumented Systems(SIS):In safety-critical applications such as emergency shutdown systems(ESD)and fire and gas detection(F&G)systems,these devices are used to actuate final actuators such as safety valves and alarms,ensuring safe plant operation.Critical Process Control:Used in critical control loops in industries such as oil and gas,chemicals,and power generation to control important process valves,motors,and other equipment,ensuring the stability and reliability of production processes.
Transportation:Used in railway signal control systems and subway protection systems,driving key equipment such as signal lights and switches to ensure transportation safety.
Other high-risk industries:These include nuclear power,aerospace,and other sectors with extremely low tolerance for system failures.
