TRICONEX 3401是英维思Triconex系统中的数字输出模块。

TRICONEX 3401可以更好地适用于仪表板和报告，此外，远程连接可以让服务提供商即时访问机器数据，这可以加快故障排除的速度

TRICONEX 3401电源模件：把外部电压转换成适合各Tricon模件使用的DC电源

Tricon的双冗余电池组位于机架背板上的正面，在I/O扩展口的旁边。如发生电源故障的情况，这些锂电池能够保存数据和程序，累计保持时间为六个月，所以Tricon建议每五年更换一次电池（锂电池），或者在他们累计使用六个月之后更换。

在正常环境中，两个电源模件都是工作的，每一个都向Tricon供电，这时只有PASS和POWER两个指示器灯亮(ON)，任何一个电源模件都可在一定时间内单独给机架.电源模件可以在线更换，视为热备。主机架报警指示

当下列情况下，主机架电源模块的报警接点被触发

-系统的配置不能和控制程序的配置匹配。

-数字输出(DO)模件之一出现了LOAD/FUSE错误。

-系统中某个地方的模件缺失。

-主机架内有一个主处理器或I/O模件故障。

-扩展机架中某个在线I/O模件故障。如果在某一扩展机架内的某I/O模件内有着一支路故障但还能继续正确地运行或者把控制传递给了热备，则主机架报警不会发动。

-主处理器探测到有一系统故障。在这个情况下，两个报警触点都有可能被发动二没有相应的模件故障。

-机架之间的I/O总线电缆安装不正确（列如支路A的电缆不小心被连到了支路B上）

TRICONEX 3401 is a digital output module in the Invensys Triconex system.

TRICONEX 3401 can be better suited for dashboards and reports, and remote connections allow service providers to access machine data instantly, which can accelerate troubleshooting speed

TRICONEX 3401 power module: Converts external voltage into a DC power supply suitable for each Tricon module

The dual redundant battery pack of Tricon is located on the front of the rack backplane, next to the I/O expansion port. In the event of a power failure, these lithium batteries can store data and programs for a cumulative retention time of six months. Therefore, Tricon recommends replacing the batteries (lithium batteries) every five years or after they have been in use for six months.

In a normal environment, both power modules are working, each supplying power to the Tricon. At this time, only the PASS and POWER indicator lights are on, and any power module can be individually supplied to the rack for a certain period of time. The power module can be replaced online and is considered a hot spare. Main frame alarm indication

The alarm contact of the main rack power module is triggered when

-The system configuration cannot match the configuration of the control program.

-One of the digital output (DO) modules has encountered a LOAD/FUSE error.

-A module is missing somewhere in the system.

-There is a main processor or I/O module fault in the main frame.

-An online I/O module in the expansion rack has failed. If there is a branch fault in an I/O module within an expansion rack, but it can continue to operate correctly or control is transferred to the hot standby, the main rack alarm will not be triggered.

-The main processor has detected a system malfunction. In this case, both alarm contacts may be activated without corresponding module faults.

-Incorrect installation of I/O bus cables between racks (as listed in branch A, the cables were accidentally connected to branch B)
