ABB 500MBA02 | Analog input module

ABB 500MBA02 is an analog input module from ABB, mainly used in industrial automation control systems to convert analog signals into digital signals for processing and monitoring by controllers.

-Input channel: There are usually different configurations such as 8 channels or 16 channels, which can simultaneously collect multiple analog signals.

-Input signal range: Supports multiple standard analog input signal ranges, including voltage signals such as 0-10V, ± 5V, ± 10V, etc; Current signals such as 4-20mA, 0-20mA, 

etc; It can also receive resistance signals, such as 0-1k Ω, 0-10k Ω, etc., and can be adapted to various sensors.

-Resolution: Generally 12 bit, 14 bit, or 16 bit. High resolution can improve measurement accuracy, for example, 16 bit resolution can divide the input signal range into 

65536 quantization levels.

-Accuracy: Usually up to ± 0.1% FS (full scale) or higher, ensuring the reliability of measurement results, such as maximum error not exceeding ± 10mV at full scale 10V.

-Sampling frequency: expressed in Sampling Points per Second (SPS), commonly ranging from tens of Hz to several thousand Hz, suitable for different dynamic process 

monitoring or high-speed data acquisition scenarios.

-Isolation characteristics: The input channel is isolated from other parts and external circuits through optocouplers or electromagnetic isolation technologies, with an isolation 

voltage of up to 2500V or higher, which can effectively resist electromagnetic interference and grounding issues.

-Diagnostic function: It can monitor the working status in real time, detect whether the input signal exceeds the range, whether the module is faulty, etc. When abnormalities 

are found, diagnostic information can be sent through indicator lights, alarm signals, or communication interfaces.

-Communication interface: Common industrial standard communication protocol interfaces such as Profibus DP, Modbus, CANopen, etc. are used for data transmission and 

communication with controllers such as PLC and DCS, enabling remote configuration and monitoring.

-Working temperature range: generally around -25 ℃ to+70 ℃, can adapt to different industrial environments, and can operate stably in both high and low temperature 

environments.

-Power requirements: Usually powered by a 24V DC power supply, with low power consumption, and the power input has reverse polarity protection and overvoltage 

protection functions.
