ICS Triplex T8403 是一款數(shù)字輸入模塊，具備三重模塊化冗余（TMR）特性，用于工業(yè)自動化系統(tǒng)中的數(shù)據(jù)采集和監(jiān)測。它具有以下特點(diǎn)：

每個模塊擁有40個三重模塊化冗余（TMR）輸入通道，確保了系統(tǒng)的高可靠性和容錯能力 。

模塊進(jìn)行全面的自動診斷和自檢，具備每個通道的可選線路監(jiān)控，以檢測開路和短路現(xiàn)場接線故障 。

采用2500V脈沖耐受光電/電流隔離柵，確保信號的穩(wěn)定性和安全性 。

板載事件序列（SOE）報(bào)告，具有1毫秒的分辨率，能夠精確記錄事件時(shí)間 。

模塊支持在線熱更換，使用專用的配套（相鄰）插槽或SmartSlot配置 。

前面板輸入狀態(tài)LED指示輸入狀態(tài)和現(xiàn)場接線故障，模塊狀態(tài)LED指示模塊運(yùn)行狀況和操作模式 。

此外，T8403模塊的自檢功能對于確保系統(tǒng)穩(wěn)定、安全和高效運(yùn)行至關(guān)重要，包括模塊狀態(tài)監(jiān)測、性能實(shí)時(shí)監(jiān)測、輸入通道檢測、過加速閾值檢測、故障診斷與報(bào)警、自動恢復(fù)功能以及質(zhì)量控制與測試 。

在應(yīng)用方面，T8403數(shù)字輸入模塊可用于過程監(jiān)測、設(shè)備狀態(tài)檢測、安全監(jiān)測以及數(shù)據(jù)采集和記錄 。它適用于石油化工行業(yè)、汽車制造業(yè)、電力系統(tǒng)控制、機(jī)械制造業(yè)等領(lǐng)域，可用于控制系統(tǒng)的自動化、監(jiān)控和數(shù)據(jù)采集等方面 。

ICS Triplex T8403 is a digital input module with triple modular redundancy (TMR) for data acquisition and monitoring in industrial automation systems. It has the following characteristics:

Each module has 40 triple modular redundancy (TMR) input channels, ensuring high system reliability and fault tolerance.

Modules are fully automated diagnostics and self-tests with optional line monitoring per channel to detect open - and short-circuit field wiring failures.

The 2500V pulse resistant photoelectric/current isolation gate ensures signal stability and safety.

Onboard Event Sequence (SOE) reports with a resolution of 1 millisecond, enabling accurate recording of event time.

Modules support online hot replacement using dedicated matching (adjacent) slots or SmartSlot configurations.

Front panel input status LED indicates input status and field wiring faults, module status LED indicates module health and operating mode.

In addition, the self-test function of the T8403 module is essential to ensure the stable, safe and efficient operation of the system, including module condition monitoring, real-time performance monitoring, input channel detection, overacceleration threshold detection, fault diagnosis and alarm, automatic recovery function, and quality control and testing.

In terms of applications, the T8403 digital input module can be used for process monitoring, equipment condition detection, safety monitoring, and data acquisition and recording. It is suitable for petrochemical industry, automobile manufacturing, power system control, machinery manufacturing and other fields, and can be used for automation, monitoring and data acquisition of control systems.
