IS220PAICH2A 模拟输入/输出模块

产品详情】

IS220PAICH2A 模拟量输入模块又称A/D模块，将现场由传感器检测而产生的连续的模拟量信号转换成PLC的CPU可以接收的数字量，一般多为12位二进制数，数字量位数越多的模块，分辨率就越高。

IS220PAICH2A 拟量输出模块又称为D/A模块，把PLC的CPU送往模拟量输出模块的数字量转换成外部设备可以接收的模拟量（电压或电流）。模拟量输出模块所接收的数字信号一般多为12位二进制数，数字量位数越多的模块，分辨率就越高。

IS220PAICH2A 而数字量模块就是检测外部开关量输入的状态

IS220PAICH2A 数字量输入输出信号就是开关量信号，1或者0，模拟量信号，有2种，电压或者电流信号 ，一般是变送器传过来的信号，比如用压力变器检测水管压力，它会输出一个模拟信号4–20ma 或者 0-10V的信号给PLC，PLC来进行数据处理。

Product description

IS220PAICH2A analog input module, also known as A/D module, converts the continuous analog signal generated by the sensor detection in the field into the digital quantity that the PLC CPU can receive, generally 12-bit binary number, the more digital quantity modules, the higher the resolution.

IS220PAICH2A analog output module, also known as D/A module, converts the digital quantity sent by the PLC CPU to the analog output module into the analog quantity (voltage or current) that can be received by external devices. The digital signal received by the analog output module is generally 12-bit binary number, and the more digital quantity modules, the higher the resolution.

IS220PAICH2A and the digital quantity module is to detect the status of the external switching quantity input

IS220PAICH2A digital input and output signal is the switching signal, 1 or 0, analog signal, there are two, voltage or current signals, generally the signal transmitted by the transmitter, such as the pressure transformer to detect the pressure of the water pipe, it will output an analog signal 4-20mA or 0-10V signal to the PLC, PLC for data processing.
