SCHNEIDER ILS1B853S1456    PLC自动化的作用是把现场连续变化的模拟量信号如温度、流量、电流、电压等转换成CPU能够处理的若干位数字信号。模拟量输入电路一般由运放变换、模转换（A/D）、光电隔离等组成。 PLC输入、输出模块的种类：数字输入DI,数字输出DO,模拟量输入AI，模拟量输出AO。

SCHNEIDER ILS1B853S1456    PLC自动化 数字的输入输出一般都是24V的. 模拟量的2类4种量,2类分别是电压型和电流型.电压型有0-10V和-10到10V.电流型主要有4-20MA,0-20MA.然后模块再通过A/D转换,把模拟量转换成+32767~-32768之间的数,然后再实行控制。 信号模板的作用是把各种过程i/o信号进行转换.把输入的各种信号转换成数字量,便于plc识别,处理和分析.把输出转换成模拟量给各种调节机构去执行,或将输出转换成2位式do量,去控制一些设备如启动停止、接通和断开等

The role of SCHNEIDER ILS1B853S1456 PLC automation is to convert the continuously changing analog signals such as temperature, flow, current, voltage, etc. into several digital signals that can be processed by the CPU. The analog input circuit is generally composed of op amp conversion, mode conversion (A/D), photoelectric isolation, etc. Types of PLC input and output modules: digital input DI, digital output DO, analog input AI, analog output AO.

SCHNEIDER ILS1B853S1456 PLC automation digital input and output are generally 24V. There are 4 kinds of analog quantities in 2 categories, and the 2 categories are voltage type and current type respectively. Voltage type has 0-10V and -10 to 10V. Current type mainly has 4-20MA,0-20MA. Then the module converts the analog quantity into A number between +32767 and -32768 through A/D conversion, and then implements the control. The function of the signal template is to convert various process i/o signals. The input signals are converted into digital quantities, which are easy for plc to identify, process and analyze. The output is converted into analog to various regulating mechanisms for execution, or the output is converted into a 2-bit do quantity to control some devices such as start, stop, on and off
