Trusted®TMR 24 Vdc数字输入模块接口到40个现场输入设备。容错是通过模块内40个输入通道中的每一个的三模冗余(TMR)架构实现的。
每个场的输入是三倍的，输入电压是用sigma-delta输入电路测量的。将所得到的场电压测量值与用户可配置的阈值电压进行比较，以确定所报告的场输入状态。当在现场开关处安装线路监控装置时，该模块可以检测现场电缆的断路和短路。线路监控功能为每个输入通道独立配置。三倍电压测量，加上板载诊断测试，提供全面的故障检测和容错。
该模块提供板载事件序列(SOE)报告，分辨率为1毫秒。状态的变化触发SOE条目。状态由电压阈值决定，可以在每个通道的基础上配置。

Trusted®TMR 24 Vdc数字输入模块是输入/输出(I/O)模块可信范围的成员。所有可信I/O模块共享共同的功能和形式。在最一般的级别，所有I/O模块接口到模块间总线(IMB)，提供电源并允许与可信TMR处理器通信。此外，所有模块都有一个字段

现场终端单元(FTU)是I/O模块的一部分，它将所有三个fiu连接到单个现场设备。FTU主要包含前端信号调理、现场信号过压保护和EMI/RFI滤波所需的无源元件。当安装在可信控制器或扩展器机箱中时，FTU现场连接器连接到附加在机箱后部的I/O电缆组件。
SmartSlot链路通过FTU从HIU传递到现场连接。这些信号直接进入I/O电缆组件，并与FTU上的I/O信号保持隔离。SmartSlot链路是主备模块之间的智能连接，用于模块更换过程中的协调。
现场接口单元(FIU)是模块的一部分，包含与特定类型的现场I/O信号接口所需的特定电路。每个模块有三个fiu，每个切片一个。对于TMR 24 Vdc数字输入模块，FIU包含一个单独的模拟到数字(A/D)转换器，用于40个字段输入中的每一个。
FIU从HIU接收隔离的逻辑电源。FIU为FIU电路所需的工作电压提供额外的功率调节。一个隔离的6.25 Mbit/s串行链路将每个FIU连接到其中一个HIU片。
FIU还测量一系列板载“管家”信号，以协助监控模块的性能和操作条件。
这些信号包括电源电压、电流消耗、板载参考电压和板载温度。

T8403C

The Trusted® TMR 24 Vdc Digital Input module interfaces to 40 field input devices. Fault tolerance is achieved through a Triple Modular Redundant (TMR) architecture within the module for each of the 40 input channels.
Each field input is triplicated and the input voltage is measured using a sigma-delta input circuit. The resulting field voltage measurement is compared to user configurable threshold voltages to determine the reported field input state. When a line-monitoring device is installed at the field switch, the module can detect open and short circuit field cables. Line monitoring functions are independently configured for each input channel. The triplicated voltage measurement, coupled with onboard diagnostic testing, provides comprehensive fault detection and tolerance.
The module provides onboard Sequence of Events (SOE) reporting with a resolution of 1 ms. A change of state triggers an SOE entry. States are determined by voltage thresholds that can be configured on a per channel basis.
Features
• 40 Triple Modular Redundant (TMR) input channels per module.
• Comprehensive, automatic diagnostics and self-test.
• Selectable line monitoring per channel to detect open circuit and short circuit field wiring faults.
• 2500 V impulse withstand opto/galvanic isolation barrier.
• Onboard Sequence of Events (SOE) reporting with 1 ms resolution.
• Module can be hot-replaced online using dedicated Companion (adjacent) Slot or SmartSlot (one spare slot for many modules) configurations.
• Front panel input status LEDs for each channel indicate input status and field wiring faults.
• Front panel module status LEDs indicate module health and operational mode (Active, Standby, Educated).
• TϋV Certified IEC 61508 SIL 3

The Trusted® TMR 24 Vdc Digital Input Module is a member of the Trusted range of Input/Output (I/O) modules. All Trusted I/O Modules share common functionality and form. At the most general level, all I/O Modules interface to the Inter-Module Bus (IMB) which provides power and allows communication with the Trusted TMR Processor. In addition, all Modules have a field

The Field Termination Unit (FTU) is the section of the I/O Module that connects all three FIUs to a single field device. The FTU primarily contains passive components necessary for front-end signal conditioning, field signal overvoltage protection, and EMI/RFI filtering. When installed in a Trusted Controller or Expander Chassis, the FTU field connector interconnects to the I/O cable assembly attached at the rear of the Chassis.
The SmartSlot link is passed from the HIU to the field connections via the FTU. These signals go directly to the I/O cable assembly and maintain isolation from the I/O signals on the FTU. The SmartSlot link is the intelligent connection between Active and Standby Modules for coordination during Module replacement.
The Field Interface Unit (FIU) is the section of the Module that contains the specific circuits necessary to interface to the particular types of field I/O signals. Each Module has three FIUs, one per slice. For the TMR 24 Vdc Digital Input Module, the FIU contains an individual analog to digital (A/D) converter for each of the 40 field inputs.
The FIU receives isolated power from the HIU for logic. The FIU provides additional power conditioning for the operational voltages required by the FIU circuitry. An isolated 6.25 Mbit/s serial link connects each FIU to one of the HIU slices.
The FIU also measures a range of onboard “housekeeping” signals that assist in monitoring the performance and operating conditions of the Module.
These signals include power supply voltages, current consumption, onboard reference voltages and board temperature.
