>>>>>型號(hào):DP840 I/O模塊

【功能描述】

DP840是一款I(lǐng)/O模塊，主要用于AC500CPU的本地?cái)U(kuò)展。

這款模塊具有多個(gè)通道，每個(gè)通道可用于脈沖計(jì)數(shù)或頻率速度測(cè)量，最大支持20kHz。此外，每個(gè)通道都有可配置的輸入濾波器，模塊還具有周期性的自診斷功能和高級(jí)診斷功能，適用于單個(gè)或冗余應(yīng)用。

DP840模塊特別適用于NAMUR接口，支持12V和24V傳感器信號(hào)電平。它還可以將輸入讀取為數(shù)字輸入信號(hào)，并在16位計(jì)數(shù)器中累加脈沖計(jì)數(shù)。這使得DP840在工業(yè)自動(dòng)化控制系統(tǒng)中具有廣泛的應(yīng)用前景。

DP840模塊還具備與其他設(shè)備和系統(tǒng)的通信能力。它擁有兩個(gè)集成串口，每個(gè)均可設(shè)為RS232/RS485，這使得模塊能夠與其他設(shè)備進(jìn)行數(shù)據(jù)交換和通信。此外，DP840模塊還配備有顯示屏和8個(gè)功能鍵，

方便用戶進(jìn)行診斷和狀態(tài)顯示。

在擴(kuò)展性方面，DP840模塊支持CPU集中擴(kuò)展最多10個(gè)本地輸入/輸出擴(kuò)展模塊。同時(shí)，每個(gè)CPU除集成通訊口外，最多可同時(shí)擴(kuò)展4種不同的通訊處理器以任意組合同時(shí)運(yùn)行。這種強(qiáng)大的擴(kuò)展能力使得

DP840模塊能夠滿足各種復(fù)雜的工業(yè)自動(dòng)化需求。

總的來(lái)說(shuō)，DP840是一款功能強(qiáng)大、性能穩(wěn)定的I/O模塊，適用于各種工業(yè)自動(dòng)化控制系統(tǒng)。它的多通道設(shè)計(jì)、高級(jí)診斷功能以及強(qiáng)大的擴(kuò)展能力使得它在工業(yè)自動(dòng)化領(lǐng)域具有廣泛的應(yīng)用價(jià)值。

【英文介紹】

The DP840 is an I/O module that is mainly used as a local extension to the AC500CPU.

The module has multiple channels, each of which can be used for pulse counting or frequency speed measurement, and supports a maximum of 20kHz. In addition, each channel has a configurable 

input filter, and the module also has periodic self-diagnostics and advanced diagnostics for single or redundant applications.

The DP840 module is particularly suitable for NAMUR interfaces and supports 12V and 24V sensor signal levels. It can also read the input as a digital input signal and add up the pulse count in a 

16-bit counter. This makes DP840 have a wide application prospect in industrial automation control system.

The DP840 module also has the ability to communicate with other devices and systems. It has two integrated serial ports, each of which can be set to RS232/RS485, which enables the module to 

exchange data and communicate with other devices. In addition, the DP840 module is equipped with a display screen and 8 function keys for easy diagnosis and status display.

In terms of scalability, the DP840 module supports CPU central scaling up to 10 local input/output expansion modules. At the same time, in addition to the integrated communication port, each 

CPU can expand up to 4 different communication processors to run simultaneously in any combination. This powerful scalability enables the DP840 module to meet a wide range of complex 

industrial automation needs.

Overall, the DP840 is a powerful and stable I/O module suitable for a wide range of industrial automation control systems. Its multi-channel design, advanced diagnostic function and powerful 

scalability make it widely used in the field of industrial automation.
