The ICS Triplex T8403 is a 24VDC digital input module,part of the Trusted TMR system,primarily for use in safety instrumented systems(SIS).Product details are as follows:
Basic Information
Manufacturer:ICS Triplex(now Triconex,a Schneider Electric brand)
Number of Input Channels:40,Triple Modular Redundancy(TMR)
Input Voltage:24VDC(typical),supports a 0V to 24VDC range
Input Current:2mA(typical)
Signal Type:Digital Input
Operating Temperature Range:-40°C to+70°C
Storage Temperature Range:-55°C to+85°C
Features:Triple Modular Redundancy(TMR)architecture:Provides high availability for each input channel,ensuring accurate input signal output even in the event of partial component failure.
High-Precision Voltage Measurement:Each field input is tripled,and sigma-delta input circuitry accurately measures the input voltage to determine the reported field input status.User-configurable thresholds:Customizable input threshold voltages are possible based on different field device types,enhancing the module’s adaptability.
Line monitoring:Detects open and short-circuit conditions on field cables,and line monitoring is independently configurable for each input channel.
Comprehensive diagnostics:Automatic diagnostics and self-test capabilities enhance module reliability.
Sequence of Events(SOE)reporting:Integrated onboard SOE reporting with 1 millisecond resolution triggers an SOE entry for any state change,accurately recording input state changes.
High-voltage isolation:Equipped with a 2500V pulse-withstand optical/galvanic isolation barrier for enhanced safety.
Hot-swappable:Online hot-swappable modules can be configured using dedicated mating(adjacent)slots or intelligent slots,reducing downtime during maintenance.
Status indication:Each channel on the front panel features an input status LED that indicates input status and field wiring faults.A module status LED indicates module health and operating mode(active,standby,or backup).Safety Integrity Level:TÜV IEC 61508 SIL 3 certified,suitable for industrial scenarios with extremely high safety requirements.
