Products Description
Structure and Measurement Principle
Basic module information
Model: 500BIO01
Order number/part number: 1MRB150005R1-J (or written as 1MRB150005R1/J)
Manufacturer: ABB
Product series: AC 500 series I/O modules (belonging to distributed or local I/O expansion modules)
Type: High speed digital input/output (DI/DO) control module ("high-speed type" usually refers to supporting fast response or high-frequency signal processing)
⚡ Core performance parameters (high-speed characteristics)
Project parameter description
Input voltage 24 V DC (typical industry standard)
Digital input (DI) supports high-speed counting and pulse capture, with a response time of ≤ 10 µ s (depending on the configuration)
Digital output (DO) transistor output, supporting high-frequency switching (such as 100 kHz pulse output, used for stepper/servo control)
The common number of channels is 8/16 channel DI or DO, or mixed configuration (specific sub models need to be checked)
Isolation level: Electrical isolation between channels and power/logic rooms (usually ≥ 500 V AC)
The communication interface communicates with AC 500 CPU (such as 500CPU05) at high speed through the backplane bus, with a synchronization period of less than 1 ms
Installation method: DIN rail installation, modular plug-in design
Key features and functions:
Overcurrent protection: Detects excessive current flowing through the transformer and initiates appropriate protective actions to prevent damage.
Differential protection: Compares the currents flowing into and out of the transformer to detect internal faults within the transformer windings.
Bucking protection: Protects against short circuits between the high-voltage and low-voltage windings of the transformer.
Overheating protection: Monitors the temperature of the transformer and initiates protective actions if it exceeds safe limits.
Gas detection: Detects the presence of gases produced by faults within the transformer, such as hydrogen or carbon monoxide, and initiates appropriate actions.
Communication: Communicates with other system components, such as the substation control system and protection relays, to coordinate protection and control functions.
Applications:
Substations: Used in various types of substations, including power generation, transmission, and distribution substations.
Industrial facilities: Employed in industrial facilities that require reliable and efficient power distribution, such as manufacturing plants, data centers, and hospitals.
Grid systems: Utilized in electrical grid systems to protect power transformers and ensure system stability.
