24个I/O（0/5V）接口触发（其中前4个具有隔离功能，可输入各类电平数字信号，也可与其他一起外接控制按钮）
一个RS232双向通讯控制接口，用于外部通讯输入
一个可编程双向电脑通讯接口，用于程序传输
二个RS232独立双向输出口，各输出口采用驱动芯片，支持到3-5个RS232口并联，用于控制外部通讯设备
前面板具有24个I/O触发状态显示：某个I/O处于工作状态则相对应这个I/O的指示灯亮
各I/O接口触发具有延时和同步发码功能，延时支持从一毫秒到七万小时
24个I/O触发通讯数据可支持到255条代码，形成丰富的程序场景，完成各项预设指令动作！自定义的多组通讯代码，每组支持20个以上数据指令，同时支持多个数据位，和通讯拨特率
任一个I/O口处于短路状态，具有优先权
RS232通讯串口控制，具有I/O口控制同样的状态显示功能
采用标准的1U，19英寸机柜安装方式
24 I/O (0/5V) interface triggers (the first 4 of them have the isolation function and can input all sorts of electrical level digital signals, and can also be connected to the control buttons along with other triggers
One RS232 dual way communication control interface is used for the input of external communication.
One programmable dual way computer communication interface is used for the transmission of programs.
The two RS232 independent bidirectional outputs adopt driving chips to support the parallel connection of 3~5 RS232 ports to control the external communication equipments.
The front panel has 24 I/O triggering status displays. When a I/O is in the working status, then the corresponding indicator lamp of this I/O is lit up.
The trigger of the I/O interfaces has the time delay and synchronous code sending functions, and the range of time delay is from 1ms to 70,000 hours.
The 24 I/O trigger communication data support up to 255 codes, forming abundant program scenes and accomplishing all sorts of preset instruction movements! There are multiple groups of custom communication codes, each group can support over 20 data instructions, and several data bits and communication baud rates;
Any I/O port in the short circuit state has the priority
The RS232 communication serial interface control has the same status displaying function as I/O port control 
Use the standard 1U, 19 inch machine case installation method.
