Description
The ABB DAI04 is an advanced analog input module designed for precise data acquisition in industrial automation. Built for demanding environments, it provides high accuracy, reliability, and durability, making it suitable for continuous operation under varying temperature and load conditions.
Applications
Water treatment plant: Remotely acquires pressure, flow rate, and water quality transmitter signals from different pump units.
Cement plant: Monitors differential pressure in dust filtration systems and speed feedback from each unit.
Cigarette factory: Used for monitoring ambient temperature and humidity, and for acquiring analog signals from the drying machine.
Metal processing plant: Acquires signals from multiple temperature sensors in large heat treatment furnaces.
Paper mill: Monitors pressure on paper machine rollers and provides feedback for multi-stage tension control.
Troubleshooting
Dead or fluctuating numerical values: Check if the external transmitter power supply is stable and confirm that the negative signal terminal forms a loop with the module's COM terminal.
Module error (Error light): Check if there is a conflict between the station number defined by the base DIP switch or if the master station program configuration has selected the correct DAI04 mapping.
Bus disconnection: Check for physical wear on the shielded twisted pair cable and ensure that the terminating resistor at the end of the bus is functioning properly.
FAQ
Q: What is the DAI04?
A: It is an Analog Input Module.
Q: Can the DAI04 be directly connected to a three-wire transmitter?
A: Yes, as long as the transmitter's signal line is connected to the input terminal, and the common terminal shares ground with the module's 0V reference point.
Q: What should I do if two channels of the DAI04 are idle?
A: It is recommended to disable idle channels in the software configuration or short-circuit the idle terminals to prevent interference and errors caused by induced current.
Q: What is the difference between the DAI04 and the DAI03 model?
A: Usually, the difference lies in the signal accuracy or the supported input range. The DAI04 is a more universal standard model.
Q: What is the highest ambient temperature the DAI04 module supports?
A: Industrial-grade design, the standard operating range is typically between -25 °C and +60 °C.
