ABB Electrical 1SVR630120R3100 CT-ARS.11 Time Relay

Basic Introduction

ABB Electrical 1SVR630120R3100 CT - ARS.11 Time Relay is a time relay. It is mainly used in electrical control systems to control the on-off of circuits in accordance with a pre-set time delay, and is a key element in the realisation of time-sequential control and timed operation.

Functional features

Time Delay Function

Precise time delay function. The delay time can be set according to the user's needs, and the range of delay time is wide, from a few milliseconds to several hours. For example, in the control of industrial automated production lines, if there is a need to delay a period of time after a device is started before starting another device, this can be achieved by this time relay. By adjusting its internal time-setting parameters, it is possible to accurately control the delay time and ensure that the start-up sequence between devices matches the requirements of the production process.

Multiple time delay modes

Multiple time delay modes are supported, such as power-on delay (starting from energising the relay coil and activating the contacts after reaching the set time) and power-off delay (starting from de-energising the relay coil and activating the contacts after reaching the set time). This flexibility makes it possible to adapt to different control scenarios. For example, in a lighting control system, the power-on delay mode can be used to achieve the effect of gradual lighting; the power-off delay mode allows the lights to be delayed off after the system is powered off, providing sufficient lighting time for personnel evacuation.

High Precision Timing

Timing accuracy is high, and the error range is usually within a certain percentage of the set time, which ensures the accuracy of time control. The timing principle may be based on internal high-precision crystals or other stable timing circuits, which are not greatly affected by external environmental factors (such as temperature, voltage fluctuations, etc.). It is able to provide reliable time control in applications where time accuracy is critical, such as precision automated processing equipment control and timing test equipment.

Multi-function contact output

With multiple contacts, including normally open and normally closed contacts, and a contact capacity that meets certain load requirements. These contacts can be used to control the on/off of other electrical devices such as contactors, relays, signal lamps etc. For example, in a motor control system, a normally open contact of a time relay can turn on the motor's starter contactor to start the motor when a delay time is reached; a normally closed contact can be used for interlock control to prevent other devices from starting at an inappropriate time.

Intuitive operation and display

Usually has a simple and intuitive operation interface for time setting and mode selection. It may be equipped with a digital display or indicator lamps to show the current set time, operating mode and status of the relay. This allows the user to quickly understand the operating condition of the relay during on-site commissioning and maintenance, reducing troubleshooting time. For example, the digital display makes it clear how many seconds or milliseconds the set delay time is, and whether the relay is currently in the process of timing.

Reliability and Stability

Adopting high-quality electronic components and reliable circuit design, it has good anti-interference ability and can work normally in complex electromagnetic environment. Its shell generally has a certain level of protection, which can prevent the influence of dust, moisture and other external factors on the internal circuitry, ensuring long-term stable operation in industrial environments or other harsh conditions. For example, in the factory floor, there are a large number of motors, frequency converters and other equipment generated by electromagnetic interference, the time relay can be unaffected, continue to accurately complete the time control task.

Application Areas

Industrial automation

Widely used in industrial production processes, such as chemical, pharmaceutical, food processing and other industries. In chemical production, it is used to control the charging time and stirring time of the reactor; in the pharmaceutical industry, it is used to control the drying time and sterilisation time during the production of drugs; in food processing, it is used to control the steaming time and baking time, etc. to ensure the standardisation and automation of the production process.

Building Electrical Systems

There are important applications in the lighting system and HVAC (heating, ventilation and air conditioning) system of buildings. In the lighting system, it realises functions such as timed switching on and off of lights and switching of lighting scenes, etc. In the HVAC system, it controls the timed starting and stopping of air-conditioning units, timed switching of fans, etc., in order to achieve energy-saving and comfort control.

Power system automation

In substations, distribution rooms and other power facilities, it is used to control the timing operation of various equipment, such as the timing casting and cutting of capacitor banks to improve the power factor of the power system, and the timing reset of signalling relays, etc., to ensure the safe and stable operation of the power system.

Transport and logistics automation

It plays a role in ports, airports, warehousing and logistics centres. In the crane control system of ports, it is used to control the time delay of the crane's lifting and descending actions to ensure the safety and accuracy of cargo lifting; in the warehousing and logistics centre, it is used to control the access time of the goods in the automatic racking system, and the timing operation of the conveyor system, etc., to improve the efficiency of logistics.
