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。

诊断

对接线板上的组件执行以下诊断测试：

测量激励电压。如果激励低于标称电压的 40%，I/O 组件/板会设置并锁定诊断警告。

作为测试，所有接线板的输入都设置为断开触点（故障安全）状态。任何未通过诊断测试的输入都会被强制进入故障安全模式，从而导致故障的产生。

如果来自该板的输入与来自所有三个板的 TMR 表决值不匹配，则会发出故障。

每个端子板连接器都有自己的 ID 设备，I/O 包/板会查询该设备。

Controls

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.

diagnosis.

Perform the following diagnostic tests on the components on the patch board:

Measure the excitation voltage. If the excitation falls below 40% of the nominal voltage, the I/O component/board sets and locks a diagnostic warning.

As a test, all panel inputs are set to the disconnected contact (fail-safe) state. Any input that does not pass the diagnostic test is forced into fail-safe mode, resulting in a failure.

If the input from that board does not match the TMR voting values from all three boards, a fault is issued.

Each terminal board connector has its own ID device, which is queried by the I/O packet/board.
