IS220PAICH2A模擬量輸入模塊又稱A/D模塊，將現場由傳感器檢測而產生的連續(xù)的模擬量信號轉換成PLC的CPU可以接收的數字量，一般多為12位二進制數，數字量位數越多的模塊，分辨率就越高。
IS220PAICH2A是通用電氣公司開發(fā)的模擬I/O模塊。它是Mark VIe Speedtronic控制系統(tǒng)的一部分。這個I/O包直接連接到終端板上。I/O包通過一個DC-37引腳連接器連接到單工端子板。如果只安裝了一個I/O包，支持tmr的終端板有三個DC-37引腳連接器，可以在單工模式下使用。所有這些連接都由I/O包直接支持。

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 is an analog I/O module developed by General Electric. It is part of the Mark VIe Speedtronic control system. This I/O packet is connected directly to the terminal board. The I/O packet is connected to the simplex terminal board via a DC-37 pin connector. If only one I/O package is installed, the TMR-enabled terminal board has three DC-37 pin connectors that can be used in simplex mode. All of these connections are directly supported by I/O packages.
