PACIFICSCIENTIFIC PC3406AI-001-E伺服驱动器输入/输出卡传感器、按钮、开关、继电器、螺线管甚至网络设备与连接到I/O卡上的螺丝端子的I/O信号共享信息。可以根据每台机器和设施的需要选择这些卡。在一些小型PLC中，I/O端子不是模块化卡，而是方便地安装在PLC的侧面。由于I/O设备结构种类繁多，分立和模拟模块的种类繁多，模拟模型的术语有“源”与“灌”，“电压”与“电流”。编程设备和人机界面PLC本身之外有两个非常重要的组件：编程设备和人机界面(HMI)。编程设备可以是来自同一制造商的台式计算机、膝上型计算机或手持式仪器。一些小型PLC甚至在前面有按钮，可以在不需要计算机的情况下对非常基本的逻辑操作进行编程。

谈到PLC向外部设备、仪表发送信号，有一种情况经常遇到:要求PLC的输出即能给显示仪表，又能传送给变频器一类的设备。欲彻底解决干扰问题，推荐使用隔离式信号分配器。这种隔离器PACIFICSCIENTIFIC PC3406AI-001-E伺服驱动器即实现PLC输出信号与外设隔离，同时实现外设之间隔离。有时现场仪表在配套时，由于协调不利，产生了如下情况，接收信号设备(例如接收420mA)接口连接为两线制方式也即接收口为一个24V电源与一个250Q相串联接口两根线:一个为24V正极，一个为250Q一端，适于连接现场两线制变送器。假如现场设备为四线制变送器，输出4-20mA。这样进行直接连接将造成电源冲突。解决方法是采用隔离器将现场来的4-20mA接收并隔离，在隔离器的输出部份接入一个标准的两线制变送器，以应对接收设备的接口。

PACIFICSCIENTIFIC PC3406AI-001-E Servo drive input/output card sensors, buttons, switches, relays, solenos and even network devices share information with the I/O signals connected to the screw terminals on the I/O card. These cards can be selected according to the needs of each machine and device. In some small PLCS, the I/O terminals are not modular cards, but are conveniently mounted on the side of the PLC. Due to the wide variety of I/O device structures and the wide variety of discrete and analog modules, the terms of the simulation model are "source" and "perfusion", "voltage" and "current". There are two very important components outside the PLC itself: the programming device and the Human Machine interface (HMI). The programming device can be a desktop computer, laptop, or handheld instrument from the same manufacturer. Some small PLCS even have buttons on the front that allow very basic logic operations to be programmed without the need for a computer.

When it comes to PLC sending signals to external devices and instruments, there is a situation that is often encountered: the output of the PLC is required to be given to the display instrument, and it can be transmitted to a type of equipment such as frequency converter. To completely solve the interference problem, the use of isolated signal splitter is recommended. This isolator PACIFICSCIENTIFIC PC3406AI-001-E servo driver realizes the isolation of PLC output signal and peripherals, and realizes the isolation between peripherals. Sometimes when the field instrument is matched, due to unfavorable coordination, the following situation occurs, the receiving signal device (such as receiving 420mA) interface is connected to the two-wire system, that is, the receiving port is a 24V power supply and a 250Q series interface two wires: one is a 24V positive electrode, and one is a 250Q end, which is suitable for connecting the on-site two-wire transmitter. If the field equipment is a four-wire transmitter, the output is 4-20mA. This direct connection will cause power supply conflicts. The solution is to use an isolator to receive and isolate 4-20mA from the field, and connect a standard two-wire transmitter to the output part of the isolator to deal with the interface of the receiving device.
