ABB Electrical 1SVR405501R1010 Pluggable interface relay - 10 piece minimum

Basic Introduction

The ABB Electrical 1SVR405501R1010 is a pluggable interface relay. Supplied in packs of 10 pieces minimum, this relay performs a variety of functions such as signal conversion, isolation and control in electrical control systems.

Functional Features

Signal Conversion Function

As an interface relay, it is capable of efficient signal conversion. Control signals can be converted from one voltage level or signal type to another to suit the connection between different electrical devices. For example, in an automation system containing equipment of multiple voltage levels, it can convert signals from 24V DC control circuits to drive signals suitable for 110V AC load equipment, thus enabling co-operation between devices.

Electrical isolation function

Provides excellent electrical isolation. This is important in preventing electrical interference and protecting sensitive equipment. For example, in an industrial environment, when a device is subjected to electromagnetic interference or an electrical fault, the interface relay can isolate the interference or fault from other connected devices, ensuring the stability and safety of the entire electrical system.

Pluggable Design Advantages

Pluggable features offer great convenience. During installation and maintenance, the design allows for quick replacement of relays without the need for complex wiring operations. If a relay fails, simply pull it out and replace it with a new one, greatly reducing maintenance time and system downtime. For example, in a production line control system where uninterrupted operation is critical, when a relay fails, it can be replaced quickly so that production can return to normal as soon as possible.

Multi-Contact Configuration

Typically have multiple contacts, including normally open (NO) and normally closed (NC) contacts. These contacts can be flexibly configured to control different circuits according to actual control requirements. For example, a normally open contact can be used to activate a device, while a normally closed contact can be used to trigger an alarm circuit in the event of a device malfunction, enabling a variety of control and monitoring functions.

Technical Parameters

Electrical parameters

These include parameters such as rated voltage (e.g. control coil voltage, contact voltage) and rated current (control coil current, contact current). The specific rated voltage and current values determine the conditions under which the relay can operate properly and the size of the load it can control. For example, the control coil may be 12V DC or 24V DC, the contact voltage ratings may cover common AC and DC voltage levels, and the contact current ratings are adequate for controlling devices within a certain power range.

Response Time

Response time is an important performance indicator that refers to the time it takes from the time the relay receives an input signal to the time the output contact operates. A short response time is critical for control systems with high time requirements (e.g., high-speed automated production lines) to ensure fast response and precise control.

Insulation Performance

With good insulation performance, insulation resistance and withstand voltage and other parameters in line with the relevant standards. This ensures that the relays can work properly in harsh environments such as high voltage or humidity, and there will be no leakage and other safety hazards, ensuring the safety of the electrical system.

Fields of application

Industrial Automation

Widely used in various industrial automation production lines, such as automotive manufacturing, electronic production, machining and other industries. In the automotive production line, it is used to control the movement of robots, the start and stop of welding equipment, the operation of the conveyor system, etc. In the electronic production, it is used to control the operation of circuit board test equipment, automated plug-in equipment and so on.

Intelligent Building System

There are important applications in the lift control system, lighting control system, HVAC (heating, ventilation and air-conditioning) system and other aspects of the building. In the lift control system, it is used to control the position detection of the lift car, door machine control, etc. In the lighting control system, it is used to achieve the functions of group control of lights, scene switching, etc. In the HVAC system, it is used to control the starting and stopping of the fans, pumps, and other equipments as well as the switching of operation modes.

Power system automation

In power facilities such as substations and distribution rooms, it is used for signal processing and control logic. For example, it is used to control the conversion and transmission of auxiliary signals of circuit breakers, action signals of protection devices, etc., to ensure the safe and stable operation of power systems.
