3004 增强型处理器模块A.提供三重模块化冗余结构(TMR) ，三个相同的子电路，每个子电路执行独立程度的控制。还有-个专用的硬件/软件架构，用于对输入和输出进行“投票”。能够耐受恶劣的工业环境。
C、可现场安装，可现场在线模块级安装维修，不干扰现场接线。
D.支持多达118个1/O模块(模拟和数字)和可选的通信模块。通讯模块可以连接到Modbus主机和附属设备，或Foxboro和霍尼韦尔分布式控制系统(DCS)、对等网络中的其他Tricon以及TCP/IP网络.上的外部主机。
E.可以支持距离主机远12公里的远程/O模块。
F.使用基于Windows NT系统的编程软件开发和调试控制程序。
G.输入和输出模块中的智能功能，以减少主处理器的工作量。每个/O模块有三个微处理器。输入模块的微处理器过滤和修复输入并诊断模块上的硬件故障。输出模块微处理器为输出数据的投票提供信息,通过输出端的反馈回路电压检查输出状态的有效性，并可诊断场线问题。
H.提供全面的在线诊断和修复能力。
I.日常维护可以在Tricon启动并运行时进行，而不会中断控制过程。
J.为I/O模块提供"热备”支持,可以在某些不能及时提供服务的危急情况下使用。
A. Provide a Triple Modular Redundant Structure (TMR) with three identical sub circuits, each of which performs a degree of independent control. There is also a dedicated hardware/software architecture for 'voting' on inputs and outputs. Capable of withstanding harsh industrial environments.
C. Can be installed on-site, can be installed and repaired at the module level online, without interfering with on-site wiring.
D. Supports up to 118 1/O modules (analog and digital) and optional communication modules. The communication module can be connected to Modbus hosts and ancillary devices, as well as Foxboro and Honeywell distributed control systems (DCS), other Tricon in peer-to-peer networks, and external hosts on TCP/IP networks.
E. It can support remote/O modules up to 12 kilometers away from the host.
F. Develop and debug control programs using programming software based on the Windows NT system.
G. Intelligent functions in the input and output modules to reduce the workload of the main processor. Each/O module has three microprocessors. The microprocessor of the input module filters and repairs inputs and diagnoses hardware faults on the module. The output module microprocessor provides information for voting the output data, checks the effectiveness of the output state through the feedback circuit voltage at the output end, and can diagnose field line problems.
H. Provide comprehensive online diagnosis and repair capabilities.
I. Daily maintenance can be carried out during Tricon startup and operation without interrupting the control process.
J. Provide "hot standby" support for I/O modules, which can be used in critical situations where services cannot be provided in a timely manner.
