DATAFORTH模块SCM5B38系列产品介绍
每个SCM5B38应变计输入模块提供了一个单通道的应变计输入，它被过滤、隔离、放大和转换为一个高水平的模拟电压输出。这个电压输出是逻辑开关控制的，它允许这些模块共享一个共同的模拟总线，而不需要使用外部多路复用器。
SCM5B38可以与全桥或半桥传感器接口，标称电阻为100 Ohm到10 kOhm。一对匹配的完桥电阻(在+10V激励下达到±1mV)允许使用低成本的半桥或四分之一桥传感器。10kHz的带宽允许测量高速过程，如振动分析。
输入信号通过隔离屏障场侧的预放大器进行处理。该前置放大器的增益-带宽乘积为5MHz，带宽限制在10kHz。在放大后，输入信号被一个专有的斩波器电路进行斩波。隔离由变压器耦合提供，同样使用专有技术来抑制共模尖峰或电涌的传输。该模块采用+5VDC，±5%供电。
SCM5B38模块上的特殊输入电路提供信号输入和隔离励磁电源的保护，电压高达240VAC。
Each SCM5B38 Strain Gage input module provides a single channel of strain gage input which is filtered, isolated, amplified, and converted to a high-level analog voltage output. This voltage output is logic switch controlled, which allows these modules to share a common analog bus without the requirement of external multiplexers.
The SCM5B38 can interface to full-bridge or half-bridge transducers with a nominal resistance of 100 Ohm to 10 kOhm. A matched pair of bridge-completion resistors (to ±1mV at +10V excitation) allows use of low cost half-bridge or quarter-bridge transducers. The 10kHz bandwidth allows measurement of high speed processes such as vibration analysis.
The input signal is processed through a pre-amplifier on the field side of the isolation barrier. This pre-amplifier has a gain-bandwidth product of 5MHz and is bandwidth limited to 10kHz. After amplification, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges. The module is powered from +5VDC, ±5%.
Special input circuits on the SCM5B38 module provide protection of the signal inputs and the isolated excitation supply up to 240VAC.
