DR-IO系列DIN轨道安装输入/输出模块是将现实世界离散信号连接到计算机接口和其他电子设备的理想选择。大多数计算机接口只能检测或生成低电平TTL（0/5 Vdc）信号。DR-IO-OAC和DR-IO-ODC输出模块可用于感应高电平的交流和直流信号。DR-IO模块的紧凑设计允许高密度安装在标准DIN导轨上。输入模块有负逻辑和正逻辑版本。负逻辑模块在字段输入信号变低时产生高逻辑信号，在字段输入变高时产生低逻辑信号。对于正逻辑模块，逻辑信号跟随现场信号；即，现场信号高时，逻辑信号高；现场信号低时，逻辑信号低。

DR-IO Series DIN rail mount input/output modules are ideal for connecting real world discrete signals to a computer interface and other electronic equipment. Most computer interfaces can only sense or generate low level TTL (0/5Vdc) signals. The DR-IO-OAC and DR-IO-ODC output modules can be used to sense high level ac and dc signals. The compact design of the DR-IO modules permit high density mounting on a standard DIN rail. The input modules are available with negative and positive logic versions. Negative logic modules produce a high logic signal when the input signal from the field goes low and a low logic signal when the field input goes high. With the positive logic modules, the logic signal follows the field signal; that is, the logic signal is high when the field signal is high and low when the field signal is low.
