E5EAA HENF105240R1 数字量输出模块 具有隔离和功率放大的作用

E5EAA HENF105240R1 数字量输出模块是将控制器程序运算的逻辑结果（0或1的BOOL型数据）送到模块通道外，转换成外部的驱动信号，通过模块接线端回路打开或关闭外部开关。该模块将PLC的内部信号电平转化为控制过程所需的外部信号电平，同时有隔离和功率放大的作用。输出模块的功率放大元件包括驱动直流负载的大功率晶体管和场效应晶体管、驱动交流负载的双向晶闸管或固态继电器，以及既可以驱动交流负载又可以驱动直流负载的小型继电器。数字量输出模块的输出电流典型值为0.5~2A，负载电源由外部现场提供。在混砂车自动控制系统中，负载所需要的驱动信号主要是直流信号（24V）。此外，数字量输出模块的信号数量相对较少，主要包括发动机启动、液压倾斜阀门、发动机冷风扇等。E5EAA HENF105240R1 数字量输出模块的特点主要包括以下几个方面：多样性：数字量输出模块有多种类型，如继电器输出型、开漏输出型、开关量输出型和模拟量输出型等。

These different types of modules have their own characteristics and can meet various application needs. High precision and stability: The digital output module can achieve high-precision and high stability digital display, and various display effects can be achieved through control chips. Intelligence: Some digital output modules have intelligent characteristics, such as self diagnosis function, which can automatically reset and restart in case of module failure during operation. Security: The design of the digital output module takes into account safety factors, such as the fuse protection for each output group, which can automatically protect the module in case of overload; In addition, each output adopts a password lock function to ensure that there will be no misoperation or rejection. Usability: The hardware of the E5EAA HENF105240R1 digital output module does not need to be set, and the CPU module can automatically load parameters on it after startup; Meanwhile, some modules support hot swapping, making module replacement and maintenance more convenient. In practical applications, the selection of digital output modules should be based on the type and magnitude of load voltage, operating frequency, and type of load (such as resistive, inductive, mechanical, or incandescent lamp loads). In addition, to maintain channel margin, it may be necessary to choose modules with more digital output channels.
