數(shù)字輸出模塊 每個 TMR 數(shù)字輸出模塊都有三組獨立的電子設(shè)備，稱為通道，它們獨立地接受來自與每個通道相關(guān)聯(lián)的 MP 的數(shù)據(jù)。這些通道使用獲得專利的 Quad Voter 電路來對施加到負載的各個輸出信號進行投票。如果三個開關(guān)中的兩個（通道 A 和 B，或通道 B 和 C，或通道 A 和 C）命令它們關(guān)閉，則該表決器電路基于并行串聯(lián)路徑傳遞功率。
Quad Voter 電路在所有關(guān)鍵信號路徑上具有多重冗余，確保安全性和可用性。對于每個點，DO 模塊定期執(zhí)行輸出投票者診斷 (OVD) 例程。為了在各種多故障情況下實現(xiàn)不受限制的安全操作，OVD 檢測并發(fā)出以下類型的故障警報：
? 點——所有卡住和卡住都在不到 500 毫秒內(nèi)被檢測到。
? 開關(guān)——檢測所有卡住或卡住的開關(guān)或其相關(guān)驅(qū)動電路。DO 模塊包括針對每個通道的完整、持續(xù)的診斷。如果診斷檢測到任何通道出現(xiàn)故障，則故障指示燈將亮起并激活系統(tǒng)警報。故障指示燈識別通道故障，而不是完整的模塊故障。DO 模塊可保證在出現(xiàn)單個故障時正常運行，并且可能會在出現(xiàn)某些多個故障時繼續(xù)正常運行。DO 模塊支持熱備用模塊。每個 DO 模塊都采用機械鍵控，以防止在配置的基板中安裝不當。

這些底板可與 3401 型 DO 模塊一起使用：
? 2401 型，用于典型應(yīng)用。
? 2401L 型，用于需要整體限流的低電流應(yīng)用。每個輸出都配有一個 180 歐姆的串聯(lián)電阻。
? DO 外部終端底板，與高壓應(yīng)用中的繼電器輸出外部終端面板或 9671-610 型 DO 危險場所外部終端面板一起使用。
Quad voter circuit has multiple redundancy on all critical signal paths to ensure safety and maximum availability. For each point, the do module periodically executes an output voter diagnostic (OVD) routine. In order to achieve unrestricted safe operation under various multi fault conditions, the OVD detects and issues the following types of fault alarms:
? point - all jams and jams are detected in less than 500 milliseconds.
? switches - detect all stuck or stuck switches or their associated drive circuits. The do module includes complete and continuous diagnostics for each channel. If the diagnostic detects a fault in any channel, the fault indicator will illuminate and activate the system alarm. The fault indicator identifies a channel fault rather than a complete module fault. The do module can ensure normal operation in case of a single fault, and may continue to operate normally in case of some multiple faults. Do module supports hot standby module. Each do module is mechanically keyed to prevent improper installation in the configured substrate.
