IS215UCVEH2AE 触点输入组隔离端子板

IS215UCVEH2AE 触点输入组隔离端子板

IS215UCVEH2AE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。

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。

The IS215UCVEH2AE 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.

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.
