DATAFORTH模块SCM5B41-03D技术参数

DATAFORTH模块SCM5B40系列产品介绍

Description

Each SCM5B40 and SCM5B41 wide bandwidth voltage input module provides a single channel of analog input which is amplified, ***lated, and converted to a high-level analog voltage output. This voltage output is logic-switch controlled, allowing these modules to share a common analog bus without the requirement of external multiplexers.

The SCM5B modules are designed with a completely ***lated computer side circuit which can be floated to ±50V from Power Common, pin 16. This complete ***lation means that no connection is required between I/O Common and Power Common for proper operation of the output switch. If desired, the output switch can be turned on continuously by simply connecting pin 22, the Read-Enable pin, to I/O Common, pin 19.

The input signal is processed through a pre-amplifier on the field side of the ***lation 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. ***lation 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%.

A special input circuit on the SCM5B40 and SCM5B41 modules provides protection against accidental connection of power-line voltages up to 240VAC.

描述

每个SCM5B40和SCM5B41宽带宽电压输入模块提供单通道模拟输入，该模拟输入被放大、隔离并转换为高电平模拟电压输出。 该电压输出由逻辑开关控制，允许这些模块共享公共模拟总线，而无需外部多路复用器。

SCM5B模块设计有一个完全隔离的计算机侧电路，可以从电源公共端浮动到 ±50V，引脚16。这种完全隔离意味着I/O公共端和电源公共端之间不需要连接，输出开关的正常运行 . 如果需要，只需将引脚22（读取启用引脚）连接到I/O公共端引脚19，即可连续打开输出开关。

输入信号通过隔离栅现场侧的前置放大器进行处理。该前置放大器的增益带宽积为5MHz，带宽限制为10kHz。放大后，输入信号被***斩波电路斩波。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浪涌的传输。该模块由 +5VDC 供电，±5%。

SCM5B40和SCM5B41模块上的特殊输入电路可防止意外连接高达240VAC的电源线电压。
