H3CR-A AC100-240/DC100-125 belongs to a type of Time Delay Relays. It is mainly used for various relay-release control and timing control of automatic control system accessories, such as output state controlled by time and other special requirements related to timing. It can also be used for the control system with sequential operations requirement and regularly time-controlled system.

H3CR-A AC100-240/DC100-125 application field is wide and could be used in various circumstances. It can be used for regular time control system in appliances and equipment which require delay action, on-delay, interval, and flicker actions. One example is in an air conditioner, when the user sets timing for 15 minutes. The timer can be programmed to power off for 15 minutes, and then runs again. The timer can also be used in industrial equipment and production lines to control temperature, speed, length, quantity and other variables. It can also be used in monitoring systems to delay feedback signals for verification.

H3CR-A AC100-240/DC100-125\'s working principle is composed of two parts: timer circuit and switch circuit. Its timer circuit is based on field effect transistor (FET) and monolithic integrated circuits (ICs) which both use low voltage source and adopt single-step or double-step trigger method. Their time range is 1-60 seconds and 1-60 minutes, respectively. The switch circuit consists of DC power supply, duplex relay switch and three LEDs one green, one amber and one red. The green LED powers on when the timer runs normally, the amber LED indicates a running time out of set, and the red LED glows when the timing is finished.

H3CR-A AC100-240/DC100-125’s switching time is adjustable and this can be done by using adjustable resistors. It has high accuracy which is achieved by using electronic components, quartz oscillators, and ensuring in-merge accuracy by finely adjusting gain of electronic components. Its applicable voltage range is widely from AC100-240/DC100-125, and this is a great advantage because the same H3CR-A can be used in almost all countries due to its wide range in voltage. It features light weight, small size, and highly reliable characteristics.

Therefore, H3CR-A AC100-240/DC100-125 is a useful and versatile time delay relay which is applicable in almost all countries due to its wide voltage range and it can be used to meet different timing needs. Its timer circuit and switch circuit are combined to control different types of appliances and monitor systems.
