该模块有16个数字量输入。输入电压范围为18~30伏直流，输入电流为6ma(24)，输入分为两个单的隔离组，每个组有八个通道和一个电压监控输入。

每个输入通道由当前限制组件、EMC保护组件、输入状态指示灯和光学隔离屏障组成。电压监控输入会在电压消失时给出通道错误信号。错误信号可以通过模块总线读取。

The module has 16 numeric inputs. The input voltage ranges from 18 to 30 volts DC with an input current of 6ma(24), and the input is divided into two single isolated groups, each with eight channels and a voltage monitoring input.

Each input channel consists of a current limiting component, an EMC protection component, an input status indicator, and an optical isolation barrier. The voltage monitoring input will give a channel error signal when the voltage is lost. The error signal can be read through the module bus.
