NI PCI-6520工業(yè)數(shù)字I/O模塊的優(yōu)勢(shì)

1.產(chǎn)    品     資    料    介    紹：

NI PCI-6520是一款工業(yè)數(shù)字I/O模塊，具有高通道隔離和工業(yè)標(biāo)準(zhǔn)24 V邏輯電平。它提供16通道，包括8路漏極/源極輸入和8路繼電器輸出（60 V）。PCI?6520需要一個(gè)按鍵連接器來提高安全性。如果發(fā)生計(jì)算機(jī)或應(yīng)用程序故障，PCI?6520可以使用數(shù)字I/O看門狗切換到可配置的安全輸出狀態(tài)，以確保檢測(cè)到故障狀態(tài)并進(jìn)行安全恢復(fù)。它還具有可編程上電狀態(tài)、數(shù)字濾波和變化檢測(cè)功能，可對(duì)應(yīng)用進(jìn)行最佳控制

NI PCI-6520的優(yōu)點(diǎn)包括：

高通道隔離和工業(yè)標(biāo)準(zhǔn)24 V邏輯電平

提供可編程上電狀態(tài)、數(shù)字濾波和變化檢測(cè)功能，可對(duì)應(yīng)用進(jìn)行最佳控制

提供數(shù)字I/O看門狗切換到可配置的安全輸出狀態(tài)，以確保檢測(cè)到故障狀態(tài)并進(jìn)行安全恢復(fù)

提供了三個(gè)單刀雙擲（SPDT）C型繼電器和五個(gè)單刀單擲（SPST）A型繼電器

The NI PCI-6520 is an industrial digital I/O module with high channel isolation and industry standard 24 V logic levels. It provides 16 channels, including 8 drain/source inputs and 8 relay outputs (60 V). The PCI ? 6520 requires a key connector to improve security. In the event of a computer or application failure, the PCI ? 6520 can use a digital I/O watchdog to switch to a configurable safe output state to ensure that a failure state is detected and safe recovery occurs. It also has programmable power-on status, digital filtering, and change detection functions for optimal control of applications

The benefits of NI PCI-6520 include:

High channel isolation and industry standard 24 V logic level

Provides programmable power-on status, digital filtering, and change detection functions for optimal control of applications

Provide a digital I/O watchdog to switch to a configurable safe output state to ensure fault detection and safe recovery

Three single pole double throw (SPDT) type C relays and five single pole single throw (SPST) type A relays are provided
