TRICONEX 3721C 康吉森系统英维思
英维思 Triconex 3721在模拟输入模块上,英维思 Triconex 3721模拟量输入模块三个通道中的每一个都异步测量输入信号并将结果放入一个值表中。英维思 Triconex 3721模拟量输入模块三个输入表中的每一个都通过相应的I/O总线传递给相关的主处理器模块。每个主处理器模块中的输入表通过Tricon传输到它的邻居。中间值由每个主处理器选择,每个主处理器中的输入表相应地进行修正。英维思 Triconex 3721模拟量输入模块在TMR模式下,控制程序使用中值数据;在双工模式下,使用平均值。

Invensys Triconex 3721 On the analog input module, each of the three channels in the Invensys Triconex 3721 analog input module asynchronously measures the input signal and puts the result into a value table. The Invensys Triconex 3721 analog input module Each of the three input tables is passed to the relevant main processor module via the corresponding I/O bus. The input table in each main processor module is transmitted to its neighbors via Tricon. The intermediate value is selected by each master processor, and the input table in each master processor is corrected accordingly. Invensys Triconex 3721 analog input module in TMR mode, control program using median data; In duplex mode, the average value is used.

The Invensys Triconex 3721 analog input module offers two separate sets of 1×20 bipolar multiplexers, and the Invensys Triconex 3721 is ideal for general-purpose switches, including temperature measurements. Both sets can be automatically connected to the 3700A Series host backplane and optional DMM via an analog backplane connection relay. This connection allows hosts to reconfigure the Invensys Triconex 3721 as a single 1×40 bipolar multiplexer, or enable card-to-card extensions for larger configurations. The Invensys Triconex 3721 offers a number of other features. In addition to 40 channels, two fuse channels are available for current measurement. In addition, the Invensys Triconex 3721 includes dedicated inputs for four-wire common side ohm measurements in 40 channels. For thermocouple type measurements, automatic cold end compensation (CJC) is supported when used with type 3721-ST (screw terminal) accessories. The Invensys Triconex 3721 uses two 50-pin male D-sub connectors for signal connectivity. For screw terminals or automatic CJC, use a detachable 3721-ST type attachment.
