HE700GEN200 传导传感器板 VME机架接口 

HE700GEN200 传导传感器板 VME机架接口 

HE700GEN200是GE开发的一款触点输入组隔离端子板。24 个干触点输入连接到带组隔离的触点输入 (TBCI) 端子板上的两个栅栏式端子块。对于接触激励，TBCI 与直流电源耦合。触点输入中的降噪电路可保护浪涌和高频噪声。

TBCI 支持单工和 TMR 应用程序，并与 VTCC/VCRC 一起工作。TBCI 连接到 VME 机架，其中 VCCC 或 VCRC 处理器板通过带有模制插头的电缆放置。该板的 TBCIH B 和 TBCIH C 变体均适用于 Mark VI，并且功能相同。标称电压为 24 V dc。

HE700GEN200 安装

接线

将 24 路干接点输入的接线直接连接到端子板的两个 I/O 接线端子上。两个螺钉将这些块固定到位，并且可以将它们从电路板上拔下进行维护。每个块有 24 个端子，可容纳高达 #12 AWG 的电线。每个接线盒的左侧是一个连接到机箱接地的屏蔽接线板。

电源连接

使用插头 JE1 和 JE2 将 TBCI 连接到接触激励电压源。

布线连接

在单工系统中使用连接器 JR1 将 TBCI 连接到 I/O 处理器。使用连接器 JR1、JS1 和 JT1 将 TBCI 连接到 TMR 系统中的 I/O 处理器。根据 Mark VI、Mark VIe 或 Mark VIeS 系统的类型以及冗余级别，插入电缆或 I/O 包。

HE700GEN200 操作

在信号输入点附近的每个输入端，滤波器可降低高频噪声并控制浪涌。H1 上的干触点输入由涡轮机控制的浮动 125 V 直流 (100-145 V 直流) 电源供电。在为每个触点输入供电之前，125 V 直流母线在配电模块中受到电流限制。如规格表中所示，H2 和 H3 变体使用较低的电压。

The HE700GEN200 is a contact input group isolation terminal board developed by GE. The 24 dry contact inputs are connected to two palisade terminal blocks on the isolated contact input (TBCI) terminal board. For contact excitation, TBCI is coupled to a DC power supply. A noise reduction circuit in the contact input protects against surges and high frequency noise.

TBCI supports simplex and TMR applications and works with VTCC/VCRC. The TBCI is connected to the VME rack, where the VCCC or VCRC processor board is placed via a cable with a molded plug. Both the TBCIH B and TBCIH C variants of the board are suitable for Mark VI and function identically. The nominal voltage is 24 V dc.

HE700GEN200 installation

wiring

Connect the 24 dry contact input cables directly to the two I/O terminals on the terminal board. Two screws hold the blocks in place, and they can be unplugged from the board for maintenance. Each block has 24 terminals and can hold up to #12 AWG of wire. On the left side of each junction box is a shielded junction panel connected to the grounding of the case.

Power connection

Connect the TBCI to the contact excitation voltage source using plugs JE1 and JE2.

Wiring connection

The connector JR1 is used in a simplex system to connect TBCI to the I/O processor. Use connectors JR1, JS1, and JT1 to connect TBCI to the I/O processor in the TMR system. Depending on the type of Mark VI, Mark VIe, or Mark VIeS system and the level of redundancy, insert the cable or I/O packet.

HE700GEN200 operation

At each input near the signal input point, the filter reduces high-frequency noise and controls surges. The dry contact input on the H1 is powered by a floating 125 V DC (100-145 V DC) power supply controlled by the turbine. The 125 V DC bus is subject to current limitation in the distribution module before power is supplied to each contact input. As shown in the specification sheet, the H2 and H3 variants use lower voltages.
