ABB BN5930 safety relay

ABB BN5930 safety relay

Product Overview

ABB BN5930 safety relay is a specialized relay product developed by ABB Group for industrial safety needs, belonging to modular safety control components. The core design goal is to monitor and respond quickly to safety signals on industrial sites in real time. When dangerous conditions are detected (such as emergency stop buttons being pressed, safety doors being opened, etc.), the power or control circuits of hazardous equipment can be quickly cut off, thereby avoiding personal injury and equipment damage accidents. This product complies with international and domestic safety standards, such as EN 60947-5-1, and has stable performance and reliable security capabilities.

Core functions

The functional design of ABB BN5930 safety relay revolves around the core requirements of industrial safety control and has the following key functions:

1. Safety circuit monitoring and protection

This relay can monitor the on/off status of the safety circuit in real time, including signals from safety components such as emergency stop buttons, safety door switches, and grating sensors. When there is an open circuit, short circuit or abnormal signal in the circuit, the relay will trigger the protection action in a very short time, cut off the power supply or control signal of the controlled equipment, and ensure that the dangerous working condition is immediately terminated. Its response time is fast, usually in milliseconds, which can minimize the exposure time to danger.

2. Flexible circuit configuration capability

BN5930 supports multiple safety circuit topologies and can be configured as single channel, dual channel, or redundant channel modes according to different application scenarios. The dual channel and redundant configuration modes can effectively improve the reliability of safety circuits, avoid safety failures caused by single component failures, and meet the requirements of different safety levels (such as SIL 2, PL d, etc.). In addition, its modular design facilitates users to add or remove functional modules according to actual needs, reducing system integration costs.

3. Status indication and fault diagnosis

The product is equipped with clear LED status indicator lights, which can intuitively display the working status of the relay (such as normal operation, protection action, faults, etc.), making it convenient for on-site operators to quickly judge the equipment situation. At the same time, some models have fault memory function, which can record the type and occurrence time of the latest fault, providing important basis for maintenance personnel to troubleshoot problems and shorten the fault handling time.

4. Manual and automatic reset functions

Support manual reset and automatic reset modes, users can choose according to on-site safety regulations and operating procedures. The manual reset mode requires the operator to manually trigger the reset button after confirming that the danger has been eliminated, ensuring that the personnel can resume the operation of the equipment in a safe state; The automatic reset mode allows the relay to automatically resume operation after the safety circuit returns to normal, and is suitable for specific scenarios that do not require human intervention.

5. Anti interference capability

In response to the complex electromagnetic environment of industrial sites, BN5930 adopts advanced anti-interference design and has strong electromagnetic compatibility (EMC). It can effectively resist the influence of interference factors such as electromagnetic radiation, voltage fluctuations, and surges, ensuring stable operation under harsh working conditions and avoiding misoperation or failure caused by interference.

Applicable scenarios

ABB BN5930 safety relay, with its flexible configuration and reliable performance, is widely used in various industrial automation scenarios, especially in fields with high safety requirements, including:

1. Mechanical processing equipment

In CNC machine tools, milling machines, grinders, stamping machines and other equipment, it is used to monitor the opening and closing status of safety doors and the triggering signal of emergency stop buttons. When the operator opens the safety door for tool change, material retrieval, or presses the emergency stop button, the relay immediately cuts off the power source of the equipment to prevent the tool or moving parts from causing injury to personnel.

2. Transportation and logistics equipment

In logistics equipment such as belt conveyors, chain conveyors, and stackers, emergency stop signals and the status of protective barriers are used to monitor the equipment. When the equipment gets stuck, overloaded, or personnel accidentally enter a dangerous area and trigger the safety device, quickly stop the equipment operation to avoid equipment damage or personnel squeezing accidents.

3. Packaging and printing equipment

In packaging machines, printing machines, labeling machines and other equipment, dual hand control buttons, safety gratings and other components are used to achieve dual hand operation protection. The operator must press two control buttons simultaneously before the equipment can start, to prevent one handed operation from accidentally entering the dangerous area and ensure operational safety.

4. Automotive manufacturing production line

Used to monitor the working area of welding robots and the status of protective fences in automotive welding production lines, assembly production lines, and other scenarios. When the protective door of the robot operating area is opened or abnormal situations occur, immediately cut off the control signal of the robot, stop its movement, and ensure the safety of surrounding operators.

5. Food and beverage processing equipment

In food filling machines, beverage production lines, sterilization equipment, etc., the safety circuit used for monitoring equipment meets the strict safety and hygiene requirements of the food industry. Meanwhile, its stable performance can adapt to humid and dusty production environments, ensuring the continuous and safe operation of the production line.

-During the installation process, it is necessary to strictly follow the wiring diagram in the product manual to ensure that the wiring is firm and correct, and to avoid relay failure or equipment failure caused by wiring errors.

-Relays should be installed in a dry, ventilated, dust-free, and non corrosive gas environment, away from strong magnetic fields and high temperature heat sources, to avoid affecting their performance.

-During debugging, it is necessary to simulate various dangerous working conditions (such as triggering emergency stop buttons, opening safety doors, etc.), verify whether the protective action of the relay is accurate and rapid, and ensure that the safety function is effective.

-Regularly maintain and inspect relays, clean surface dust, check for loose wiring terminals and normal LED indicator lights, and promptly identify and address potential faults.
