　　Description: IC697ALG230 is a 90-70 series PLC basic converter module. The module was previously manufactured by GE Fanuc Automation and is now part of Emerson Automation. It is used with the IC697ALG440 current expander and IC697ALG441 voltage expander modules. The basic converter module features eight (8) differential inputs that can be configured individually for voltage or current signals, specifically 4-20 mA current input signals and -10VDC / + 10VDC voltage input signals, with a channel resolution of 16 bits.

　　The types and applications of IC697ALG230 converter modules are very diverse, and the following are two common converter modules:

　　DC-DC Converter module:

　　Definition: A DC-DC converter module is a device that adjusts the DC power supply voltage through the converter to obtain the specific voltage output required.

　　Working principle: Voltage conversion is mainly achieved by controlling the current or current flow direction. The electric energy is charged and discharged by the switching tube, filtered and adjusted by capacitors, inductors, filter circuits and other components, so as to obtain the required voltage output.

　　Function: In the communication system, the DC-DC converter module can combine the data of multiple channels and transmit it to the same channel, which greatly improves the reliability of the system.
