处理器板 IS200EPSMG2AEC 美国GE电气 隔离式 12 位模拟输出板

功能说明：

输出板 是通用电气制造和设计的单工伺服 I/O 端子板，是 GE Speedtronic 控制系统中使用的 Mark VI 系列的一部分。用于 DIN 导轨连接的小型接线板称为单工伺服输入/输出 (DSVO) 接线板。该板具有两个伺服输出、用于六个 LVDT 位置传感器的 I/O 和两个用于流量监测的有源脉冲率输入。跳线用于选择 10 到 120 mA 之间的伺服线圈电流。一根 37 针电缆，类似于更大的 TSVO 板上使用的电缆，用于将 DSVO 连接到 VSVO 处理器板。为了节省机柜空间，接线板可以垂直堆叠在 DIN 导轨上。如有必要，可以将两个 DSVO 板链接到 VSVO。该板仅以单工形式提供。

板载功能和对地高频去耦与 TSVO 上的相同。高密度 Euro-Block 型接线端子使用六个用于接地连接 (SCOM) 的螺钉 连接到电路板上。为了识别 VSVO 的板以进行系统诊断，连接器 JR1 和 J5 连接到来自板载 ID 芯片的信号。

安装：

将 DSVO 板放入塑料支架后，将其安装到 DIN 导轨上。接线端子应接收直接连接的伺服 I/O 线。Euro-Block 类型的端子块 安装在端子板上，根据版本的不同，有 42 或 36 个端子（DSVOH1B、H2B）。经常使用带#18 AWG 屏蔽的双绞线。对于 SCOM（接地）连接，提供了编号为 31 至 36 的六个螺钉；这些螺钉应在尽可能短的距离内使用。

配置：

范围从 22 W 到 1,000 W 的伺服阀线圈电阻和所需的线圈电流在 DSVOH1B 上通过跳线 JP1 和 JP2 选择。线圈电流和电阻如下表所示；例如，跳线 120B 提供大约 120 mA 的线圈电流。

Function description:

The Output board is a simplex servo I/O terminal board manufactured and designed by General Electric as part of the Mark VI series used in GE Speedtronic control systems. The small patch boards for DIN rail connections are called simplex servo input/output (DSVO) patch boards. The board has two servo outputs, I/O for six LVDT position sensors, and two active pulse rate inputs for flow monitoring. Jumpers are used to select servo coil currents between 10 and 120 mA. A 37-pin cable, similar to the one used on the larger TSVO board, is used to connect the DSVO to the VSVO processor board. To save cabinet space, the panels can be stacked vertically on DIN rails. If necessary, two DSVO boards can be linked to the VSVO. The board is only available in simplex form.

Onboard functions and high frequency decoupling to ground are the same as on TSVO. High-density Euro-Block terminals are attached to the board using six screws for ground connections (SCOM). To identify the VSVO's board for system diagnostics, connectors JR1 and J5 are connected to signals from the onboard ID chip.

Installation:

After placing the DSVO board into the plastic bracket, mount it onto the DIN rail. Terminals should receive directly connected servo I/O lines. The Euro-Block type terminal block is installed on the terminal board and has 42 or 36 terminals (DSVOH1B, H2B) depending on the version. Twisted pair with #18 AWG shielding is often used. For SCOM (ground) connections, six screws numbered 31 to 36 are provided; These screws should be used at the shortest possible distance.

Settings:

The servo valve coil resistance ranging from 22 W to 1,000 W and the required coil current are selected on the DSVOH1B via jumper JP1 and JP2. Coil current and resistance are shown in the following table; For example, the jumper 120B provides a coil current of about 120 mA.
