5501-381 数字式发动机控制系统

5501-381 是 Woodward（现为 ABB 的一部分）的一个 I/O 模块，具体为 PLC（可编程逻辑控制器）的对外功能模块。这个模块集成了 PLC 的 I/O 电路，用于通过各种 I/O 接口模块与外界进行联系。I/O 模块的数量和规格是根据所需的 I/O 点数来确定的，而这些点数又受到所能管理的基本配置的能力，即大的底板或机架槽数的限制。

具体来说，5501-381 的功能包括：

1. 输入/输出功能：模块的输入暂存器反映输入信号的状态，而输出点则反映输出锁存器的状态。这意味着模块能够接收来自各种传感器的输入信号，并根据这些信号的状态来控制输出设备或执行相应的动作。
2. 集成性：5501-381 模块通常与 PLC 的其他模块一起使用，如电源模块、底板或机架等。这些模块共同协作，实现 PLC 的各种功能，如数据采集、控制逻辑实现、通信等。
3. 扩展性：根据具体的 PLC 系统配置，5501-381 模块可能支持多种 I/O 扩展模块，以增加系统的 I/O 能力。这使得用户可以根据实际需求灵活扩展 PLC 系统的规模和功能。

The 5501-381 is an I/O module of Woodward (now part of ABB), specifically a PLC (Programmable Logic Controller) external function module. This module integrates the PLC’s I/O circuit and is used to communicate with the outside world through various I/O interface modules. The number and specifications of I/O modules are determined by the number of I/O points required, which in turn are limited by the capability of the basic configuration that can be managed, i.e. the number of large baseboards or rack slots.

Specifically, the 5501-381 features include:

Input/output function: The input register of the module reflects the state of the input signal, while the output point reflects the state of the output latch. This means that the module is able to receive input signals from various sensors and control the output device or perform corresponding actions based on the state of these signals.

Integration: The 5501-381 module is usually used with other modules of the PLC, such as the power module, backboard or rack. These modules work together to achieve various functions of PLC, such as data acquisition, control logic implementation, communication and so on.

Scalability: Depending on the specific PLC system configuration, the 5501-381 module may support a variety of I/O expansion modules to increase the system’s I/O capability. This allows users to flexibly expand the scale and functions of the PLC system according to actual needs.
