ABB DAO01｜Analog Output Module｜

DAO01

Function
Multi type analog signal acquisition (core)
Supports industrial universal 4-20mA current and 0-10V voltage signals, interfaces with pressure/temperature/flow transmitters and liquid level sensors, and converts continuous physical quantities on site into digital signals recognizable by the controller.
High precision signal conditioning and conversion
Built in 16 bit ADC analog-to-digital conversion, high measurement accuracy; Equipped with a built-in filtering circuit, it filters out electromagnetic interference caused by industrial motors and frequency converters, ensuring stable and drift free data.
Channel independent electrical isolation
Each input channel is equipped with isolation protection, with a withstand voltage of 250V AC, to prevent ground loops and surges from penetrating the main control backplane. Single channel faults will not cause the entire card to fail, ensuring continuous operation of the production line.
Built in full channel fault self diagnosis
Real time monitoring of wire breakage, short circuit, signal over range, module power supply abnormalities, panel indicator lights+system backend synchronized reporting of fault codes, on-site rapid maintenance, and reduced downtime.
Flexible parameter configuration adaptation
The software can customize the range, alarm upper and lower limits, signal stabilization time, and adapt to different process conditions such as pure water, oil and gas, and high-temperature furnaces, without the need to replace hardware.
Seamless data exchange in the system
The collected data is uploaded to the CPU through the backplane bus and connected to the 800xA screen of the central control upper computer for remote monitoring, closed-loop adjustment, and historical data recording.
