Time delay relays are electromechanical devices that are used to produce a predetermined output after a predetermined time delay. They are typically used to control the amount of time a device operates. Some devices can be used as both time delay and timer relays. In this article, we will discuss the application field and working principle of the H2C-AC120 A.

The H2C-AC120 A time delay relay is a high performance multi-function unit that is ideal for a wide variety of applications. This device is capable of up to 10 different types of delays, on/off delays, on and off delays, pulse outputs, counting operations, and memory functions. This unit has a maximum output of 120A resistive load, and it is capable of operating at temperatures ranging from -40°C to +85°C. It is designed for three-phase AC motors and auxiliary contactors.

The H2C-AC120 A is a digital time delay relay that can be programmed in a variety of ways. The unit can be programmed to control the time a device operates in a specific interval, and it can also be programmed to control the pulse frequency of the output. It also has an adjustable time-delay setting for applications requiring this feature. In addition, the unit is equipped with an input terminal for connecting the external input signal, such as a sensor or switch.

The working principle of the H2C-AC120 A is based on the principle of capacitive timing. It uses a capacitor as an energy storage element and a timer circuit to control the time-delay output signal. A programmable logic controller (PLC) is connected to the timer circuit and can be used to set the delay times. The time-delay output signal is then amplified by an amplifier circuit and sent to the load.

The H2C-AC120 A time delay relay is a reliable and versatile device that can be used in a variety of applications. It is ideal for applications such as fan shut-off and temperature protection, temperature control or humidifying systems, time-delay lamps and other lighting systems. This device is also widely used for motor protection and control, controlling air ducts and steam valves, and machine tool and process control.

In conclusion, the H2C-AC120 A time delay relay is a high performance, multi-function device that provides reliable and accurate timing control for a variety of applications. It is easy to program and can be used to control the amount of time a device operates in a specific interval. The unit is also equipped with an input terminal for connecting the external input signal, such as a switch or sensor, allowing for a variety of different applications.
