ABB 3BHT300002R1 DI620 Digital Input 32ch 24VDC

and process the collected signals in real time to further improve signal accuracy and reliability. 

Fault diagnosis and self-protection: The module has a built-in perfect fault diagnosis function, which can monitor its own working status in real time. 

Once over-voltage, over-current, short-circuit and other abnormalities are detected, 

the self-protection mechanism is immediately activated to cut off the relevant channel signal inputs to prevent the expansion of the fault; 

at the same time, it sends fault alarm information to the upper control system, which is convenient for operators to overhaul in time. 

2. High-speed data transmission

Supporting high-speed data transmission rate, it can completely and accurately transmit the collected 32 digital signals to the control system in 

a very short time. In the industrial automation production line, the equipment running state is changing rapidly, 

the high speed data transmission capability of DI620 module enables the control system to obtain the latest state information of the equipment in real time, 

make control decisions in time, and ensure the continuous stability of the production process. 

For example, in the automated assembly line of automobile manufacturing, the robot arm movement needs to 

be accurately matched with the speed of parts delivery, DI620 module can quickly transmit the position signals of the parts detected by sensors, 

which helps the control system accurately control the movement of the robot arm and realise efficient and accurate assembly. 

3. Rich Diagnostic Functions

Signal processing and analysis: With powerful signal processing functions, it not only collects and transmits digital signals, 

but also conducts in-depth analysis of the signals. By analysing the trend of sensor signal changes, 

it can predict potential equipment failures, issue early warnings, and help operators take maintenance measures to 

avoid production interruptions caused by sudden equipment failures. 

Comprehensive diagnostic function: It can carry out comprehensive diagnosis on its own hardware status, communication status and signal input status. 

Through the diagnostic information, the operator can quickly locate the fault point and judge whether it is a problem of the module itself or 

a fault of the external line or equipment. For example, when a channel signal is abnormal, 

the diagnostic function can clearly indicate whether the channel input circuit is faulty or the connected sensor is damaged, 

which greatly shortens the fault investigation time and improves the efficiency of equipment maintenance. 

Predictive maintenance support: Based on the analysis and accumulation of a large amount of equipment operation data, 

the DI620 module provides powerful support for predictive maintenance. 

Through real-time monitoring of equipment operating parameters and comparison and analysis with historical data, 

it predicts the probability and time nodes of possible equipment failures in the future, assists enterprises in formulating scientific maintenance plans, 

prepares maintenance spare parts in advance, reduces equipment maintenance costs and extends the overall service life of the equipment. 

4. Easy to integrate and expand

Seamless compatibility with ABB systems: As a member of ABB automation product family, 

DI620 module is seamlessly compatible with various control systems of ABB, such as PLC, DCS and so on. During system integration, 

the module can easily achieve communication and data interaction with the control system without complex hardware configuration and software debugging, 

which reduces the difficulty and cost of system integration and improves the stability and reliability of the whole automation system. 

Flexible expandability: When the industrial automation system is upgraded or expanded, 

DI620 module can be easily combined with other ABB I/O modules. 

By increasing or decreasing the number of modules, 

the number of system inputs and outputs can be flexibly adjusted to meet the needs of industrial applications of different scales and complexity. 

For example, in a new factory automation project, with the expansion of the production scale, 

if you need to increase the monitoring and control functions of the equipment at a later stage, 

you only need to add DI620 modules or other related I/O modules to the original control system 

to achieve the system expansion without the need for a large-scale re-design and transformation of the entire control system.
