功能特点
高精度：校准精度为0.03%，安全精度为满量程的±1%，提供精确的数据采集。
冗余设计：每个输入通道都采用TMR架构，确保系统的高可靠性和容错能力。
数字信号滤波：可对每个输入通道应用数字滤波器，单个通道可配置为高抗噪性（50Hz或60Hz抑制）、低抗噪性（快速响应）或直通操作（无滤波）。
可配置阈值：每个输入通道有四个可配置的状态阈值，可分配给事件序列（SOE）报告，状态变化会触发SOE条目，板载SOE报告的分辨率为1ms。
故障诊断：具备全面的自动诊断和自我测试功能，可检测输入是否超出范围、是否卡住等故障，自检间隔为2分钟。
隔离保护：现场公共端隔离，持续工作电压为±250Vdc，最大耐受电压为±2.5kVdc，通道间串扰为-40至-60dB，可防止电气干扰和信号串扰。
热插拔功能：支持热插拔，可使用专用的配套插槽或智能插槽配置在线热更换。
状态指示：前面板每个通道都有输入状态LED，可指示输入状态和现场布线故障；模块状态LED可指示模块的健康状况和操作模式。
安全认证：通过TÜV认证，符合IEC 61508 SIL 3安全标准，适用于安全关键型应用。
The ICS Triplex T8431 is a 24VDC analog input module featuring triple modular redundant(TMR)architecture.It is suitable for industrial automation control systems requiring high safety and reliability.The following are product details:
Basic Information
Brand:ICS Triplex
Product Type:Analog Input Module
System Supply Voltage Range:20 to 32VDC
Number of Input Channels:40
Weight:1.149kg
Input Current Range:0-22mA
Input Voltage Range:0-6VDC
Power Consumption:15-18W
Features:
High Accuracy:Calibrated accuracy of 0.03%and safety accuracy of±1%of full scale provide precise data acquisition.
Redundant Design:Each input channel utilizes TMR architecture,ensuring high system reliability and fault tolerance.
Digital Signal Filtering:A digital filter can be applied to each input channel,and individual channels can be configured for high noise immunity(50Hz or 60Hz rejection),low noise immunity(fast response),or pass-through operation(no filtering).Configurable Thresholds:Each input channel has four configurable status thresholds that can be assigned to Sequence of Events(SOE)reporting.Status changes trigger SOE entries,and the onboard SOE reporting has a resolution of 1ms.
Fault Diagnostics:Comprehensive automatic diagnostics and self-test functions detect faults such as input out-of-range and stuck conditions,with a self-test interval of 2 minutes.
Isolation Protection:Field common isolation with a continuous operating voltage of±250Vdc,a maximum withstand voltage of±2.5kVdc,and inter-channel crosstalk of-40 to-60dB protects against electrical interference and signal crosstalk.
Hot-Swap Capability:Hot-swappable and can be replaced online using dedicated mating slots or smart slot configurations.
Status Indication:Each channel on the front panel has an input status LED that indicates input status and field wiring faults.A module status LED indicates module health and operating mode.
Safety Certification:TÜV certified to IEC 61508 SIL 3 safety standards,suitable for safety-critical applications.
