1771-CFM 流量計(jì)模塊

描述:1771-CFM模塊是一種可配置的流量計(jì)模塊。它是由艾倫-布拉德利/羅克韋爾自動(dòng)化公司制造的，是PLC 5系列的一部分。1771-CFM可配置流量計(jì)模塊支持4個(gè)數(shù)字I/O，這些數(shù)字輸出在5至40伏直流電壓下工作。這個(gè)流量計(jì)模塊使用磁性拾音器，這是Bently 3300接近拾音器。1771-CFM可配置流量計(jì)模塊只需要在底盤上安裝1個(gè)槽，并通過(guò)保形涂層保護(hù)其免受腐蝕性化學(xué)品的侵害。

Allen-Bradley 1771-CFM是一個(gè)可配置的流量計(jì)模塊。它用于自動(dòng)化系統(tǒng)中，在接收到流量測(cè)量現(xiàn)場(chǎng)裝置的信號(hào)后，快速準(zhǔn)確地計(jì)算流量。也可用于軸速計(jì)算。該1771- cfm模塊是艾倫-布拉德利1771系列模塊，使plc和渦輪流量計(jì)，磁性拾起器，或單通道軸編碼器之間的接口。它也可以用來(lái)計(jì)算流量信號(hào)從任何TTL脈沖源交付。Allen-Bradley 1771-CFM用于各種行業(yè)，如發(fā)電，石油，天然氣，汽車，食品和飲料以及管道行業(yè)。操作人員幾乎可以將其用于任何流量或渦輪計(jì)量應(yīng)用。通過(guò)將該模塊安裝到PLC-5系統(tǒng)中，用戶將簡(jiǎn)化編程并節(jié)省plc的內(nèi)存。1771-CFM模塊可直接替代1771-QRC和1771-QRD模塊，無(wú)需對(duì)梯形邏輯進(jìn)行任何更改。

這種可配置的流量計(jì)模塊有四個(gè)輸入通道，它可以根據(jù)從輸入通道接收的值控制多達(dá)四個(gè)輸出。用戶可以在該設(shè)備上選擇四種操作模式:不可復(fù)位累加器模式、累加器模式、高分辨率頻率模式(通道0/1或通道2/3)和方向傳感器模式(通道0/1或通道2/3)。設(shè)備的最大輸入頻率為100khz，最大計(jì)數(shù)范圍為0 ~ 9.999.999(可編程)，最大處理時(shí)間為5.5毫秒。背板電源電流為1安培，功耗范圍為2瓦~ 13瓦。為了進(jìn)行診斷，該模塊將診斷信息以字的形式發(fā)送給PLC處理器，這些字在配置塊中可供程序員使用。該模塊應(yīng)該在0到60攝氏度(32到140華氏度)的溫度下運(yùn)行。

Description: The 1771-CFM module is a configurable type of flow meter module. It is manufactured by Allen-Bradley/Rockwell Automation as part of the PLC 5 series. The 1771-CFM configurable flow meter module supports 4 digital I/O which are digital outputs that operate at 5 to 40 Volts DC voltage. This flow meter module uses magnetic pickups which are Bently 3300 proximity pickups. The 1771-CFM configurable flow meter module only needs 1 slot in a chassis for installation and it is protected from corrosive chemicals by a conformal coating.

The Allen-Bradley 1771-CFM is a configurable flowmeter module. It is used in automated systems for the fast and accurate calculation of the flow after receiving the signal from the flow measuring field devices. It is used for shaft speed calculation too. The 1771-CFM module is the Allen-Bradley 1771 series module that makes the interface between PLCs and turbine flowmeters, magnetic pickups, or single-channel shaft encoders. It can be also used to calculate the flow signal delivered from any TTL pulse source. The Allen-Bradley 1771-CFM is used in various industries like the power generation, oil, gas, automotive, food and beverage, and pipeline industries. Operators can use it for almost any application with flow or turbine metering. By installing this module into their PLC-5 systems, users will simplify the programming and conserve memory of their PLCs. The 1771-CFM module is used as a direct replacement for 1771-QRC and 1771-QRD modules without the need for any changes to the ladder logic.

This configurable flowmeter module has four input channels and it can control up to four outputs based on the values received from the input channels. Users can select four modes of operation on this device: the non-resettable totalizer mode, totalizer mode, high-resolution frequency mode (channels 0/1 or channels 2/3), and direction sensor mode (channels 0/1 or channels 2/3). The maximum input frequency of the device is 100 kHz, the maximum count value range is 0 to 9.999.999 (programmable), and the maximum processing time is 5.5 milliseconds. The backplane power current is 1 Amp. The power dissipation ranges from 2 to 13 Watts. For diagnostic purposes, this module sends diagnostic information to the PLC processor in words that is available to programmers in a configuration block. The module should be operated at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) temperatures.
