Description

Products

ABB DSAI110 is an advanced analog input/output hybrid module for other automation fields or other fields. It simultaneously processes analog input/output signals in complex industrial process control. The module is suitable for measurement, control and monitoring of various industrial processes.

Technical parameters

Analog characteristics

Input signal range 

It can accommodate a variety of analog input signal ranges, including [specific voltage ranges, such as 0-10V, ±10V] and [specific current ranges, such as 0-20mA, 4-20mA]. This wide input range allows many different types of sensors (such as temperature sensors (output 4-20mA signals) or pressure sensors (output 0-10V signals)) to be coupled to the module to meet different industrial field measurement needs. 

Number of input channels 

It has [specific number of channels] analog input channels. By having multiple channels, signals can be read from different sources at the same time, thereby improving data acquisition efficiency. For example, in the chemical production process, it is necessary to collect temperature, pressure and other parameter signals of multiple reactors at the same time. 

Resolution and accuracy 

With high resolution, the resolution of analog input can reach [specific resolution value]. Within the entire input signal range, the accuracy can reach ± [specific accuracy value]%. High resolution and accuracy are based on ensuring signal measurement, which can distinguish small changes in the signal, provide accurate and reliable data for the control system, and make complex industrial process control possible.

Output signal range

The analog output signal range of ABB DSAI110 includes [specific voltage range, such as ±10V] and [specific current size]. The output signal can control many actuators, such as control valves that adjust the opening according to the received 4-20mA signal, converters that adjust the speed with voltage signals, and adjustable control of industrial process parameters. 

Number of output channels: 

The number of analog output channels is within the range of [specific number of channels]. Multi-channel output can control actuators in groups to enhance the control and flexibility of the system. For example, the opening of different control valves can be controlled simultaneously to distribute the flow in different pipelines. 

Linearity and stability: 

The analog output has high linearity, ensuring that the system output signal has a good linear relationship with the control given value, and the output signal has good stability. During the long-term operation of any device, the value of the output voltage or current signal rarely changes, ensuring the accuracy and reliability of the controller-driven actuator.

Electrical characteristics

Power supply requirements

Support [specific voltage range, such as 24V DC] power input. When the input is within this range, the module can work stably and provide reliable power support for the analog input and output circuit. The power supply is adaptable and can still work within the required parameter range under the existing power supply fluctuations, freeing the power supply system from strict standard restrictions. 

Power consumption

Under standard working conditions, the average power consumption is about [specific power consumption value] watts. Low power consumption design not only helps to reduce operating costs

Communication interface  and Communication protocol

Communication interface

ABB DSAI110 is equipped with a standard communication interface and supports [specific communication protocols, such as: Profibus, Modbus, etc.]. The upper control system (PLC, DCS) directly and efficiently communicates data with DSAI110 through these communication protocols. The compatibility of this communication protocol makes it very easy to integrate the module into the existing industrial automation system and establish system interconnection. 

Communication protocol

According to the selected communication protocol, the communication rate can be set to [insert communication rate value] bps. The higher the communication rate, the faster the data transmission. The control system can obtain analog input data without delay and send analog output control commands to the module, meeting the requirements of real-time control of industrial processes.

Working principle

Input Part

The analog input part of ABB DSAI110 receives the voltage or current signal generated by the sensor through the signal line and sends it to the input channel of the DSAI110 module. After amplification, filtering, sampling, processing, etc. in the module, the input signal is converted into a digital signal through h ADC and transmitted to the control system through the communication interface. 

Output Part

In the analog output part, the digital control instructions of the control system are transmitted to the module through the communication interface. The module converts the digital instructions into analog signals, and outputs the corresponding numerical or current signals to the actuator after passing through the DAC circuit and signal conditioning circuit to realize the control of the industrial process.

Product Features

Multifunctionality

Integrating analog input and output into one reduces the number of modules in the system, simplifies the system architecture, reduces costs and wiring complexity, kills two birds with one stone, meets the needs of industrial processes for a full set of analog signals, and improves the integration and flexibility of the system.

High-reliability hardware design 

Using high-quality components and advanced circuit design, it has good anti-interference performance and high reliability. When used in an industrial environment, it can resist the influence of multiplying factors such as electromagnetic interference, temperature changes, and humidity. For example, through proper grounding and shielding circuits, electromagnetic interference can be reduced, thereby ensuring the stability and accuracy of the signal. 

Fault detection and protection

The built-in fault detection mechanism can monitor the abnormal conditions of input and output signals in real time, such as signal out of range, open circuit, short circuit, etc. Overvoltage or overcurrent protection measures are also provided to deal with any possible faults. This basically ensures that the module will not fail under any abnormal conditions-improves the reliability and safety of the product.

Easy to use and maintain simple configuration 

The module's I/O range, communication parameters, etc. can be easily set through simple configuration software or tools. Users do not need to have extensive programming knowledge to correctly set the module's initialization and configuration parameters and other operational values, thus lowering the threshold for use. The transmission line terminals and interface labels of the maintenance facility module are clearly defined, which is convenient for installers and maintenance personnel to check the correct electrical connection or detect abnormal conditions. In the event of a fault, the problem can be located very quickly with the help of the module indication function or indicator light, laying the foundation for maintenance personnel to perform repair and replacement processes. In addition, it can also reduce possible downtime.

Application areas include process industries

Chemical, petroleum, power and water industries use it to collect process parameters such as temperature, pressure, flow, etc., and output control signals to adjust valve opening, pump speed, etc., thereby reducing these parameters to accurately control and optimize the production process, as well as to make the process run the safest, smoothest and most efficient. 

automated production lines

It is used to monitor and control various analog parameters on automated production lines, such as motor speed, tension control, position control, etc. With the DSAI110 module, production equipment can be accurately controlled to ensure product quality and production efficiency. 

Smart Building and Environmental Control Systems

In smart buildings, it is used to monitor environmental variables such as temperature, humidity and light, and provide control outputs for HVAC systems, lighting control and access regulations, thereby providing the basis for smart building management and energy optimization, and improving human comfort.
