描述
AI845 單極單端
AI845模擬輸入模塊用于單個或冗余應用。該模塊有8個通道。當MTU單板為TU844或TU845時,每個通道可以是電壓或電流輸入,當使用其他MTU單板時,所有通道都是電壓或電流輸入。
電壓、電流輸入不小于11v dc,電壓輸入電阻大于10m歐姆,電流輸入電阻大于250歐姆。
該模塊將外部HART兼容的發(fā)射機電源分配到每個通道。這增加了一個簡單的連接,將電源分配到2線或3線變送器。發(fā)射機功率受到監(jiān)督,電流受到限制。
特點和優(yōu)點
8通道0…20ma, 4…20ma, 0…5V或1…5直流,單端單極輸入
單一或冗余操作
1組8個通道與地面隔離
12位分辨率
當前每個信道有限的發(fā)射機供應
先進的車載診斷
HART直通通信
AI845 單極單端
The AI845 Analog Input Module for single or redundant applications. The module has 8 channels. Each channel can be either a voltage or current input when MTU TU844 or TU845 is used, when other MTUs are used all channels become voltage or current inputs.
The voltage and current input is able to withstand an overvoltage or undervoltage of at least 11 V d.c. The input resistance for voltage input is greater than 10 M ohm and the input resistance for current input is 250 ohm.
The module distributes the external HART compatible transmitter supply to each channel. This adds a simple connection to distribute the supply to 2-wire or 3-wire transmitters. The transmitter power is supervised and current limited.
Features and benefits
8 channels for 0… 20 mA, 4… 20 mA, 0…5 V or 1…5 V d.c., single ended unipolar inputs
Single or redundant operation
1 group of 8 channels isolated from ground
12 Bit resolution
Current limited transmitter supply per channel
Advanced on-board diagnostics
HART pass-through communication
