3.Application Fields

ABB DSAI145 modules are widely used in the following fields:

Electricity:Used for analog signal acquisition and conversion in power monitoring and control systems.

Petroleum:It is used to monitor and control various process parameters during oil extraction,processing and transportation.

Chemical industry:It is used to monitor the temperature and pressure of equipment such as reactors and pipelines in real time during chemical production.

Metallurgy:It is used to monitor and control the temperature,flow and pressure of equipment such as blast furnaces and converters in the metallurgical industry.

Other industrial fields:such as papermaking,textiles,food processing,etc.,also widely use DSAI145 modules for automatic control and data monitoring.

IV.Precautions for use

Impedance matching:When using the DSAI145 module,the output module of the PLC should be selected according to the input impedance of the inverter to achieve impedance matching between the two.

Voltage range:When the voltage signal range of the inverter and PLC is different,a series resistor is required to divide the voltage to ensure that both work within the normal voltage range and avoid voltage over-limit that may damage the device.

Shielding measures:For weak current control signals(such as voltage 0~5V/10V,current 0~4~20mA,etc.),they are easily interfered by strong external signals,so appropriate shielding measures should be taken,such as using shielded cables for shielding.

Wiring requirements:When actually connecting,it should be noted that the main and control cables should be wired separately and at a certain distance to ensure that the interference and noise on the main circuit side do not affect the control circuit.
