(I) DAO 02 Analogue Output Module

DAO 02 analogue output module is the upgraded model of DAO 01, which is mainly improved in the number of output channels and performance. With 4 output channels, it can drive more field actuators at the same time compared with the 2 channels of DAO 01, which is suitable for complex industrial scenarios where multiple analogue devices need to be controlled, such as multi-parameter coordinated control of large-scale chemical plants. In terms of output accuracy, DAO 02 reaches ±0.05% FS (full scale), and the resolution is upgraded to 14-bit, which enables more accurate analogue signal output to meet the needs of high-end manufacturing fields that require very high control accuracy. In terms of communication, in addition to supporting RS-485 and Modbus protocols, support for PROFINET protocol has been added, further enhancing compatibility with different control systems and communication efficiency.
