H5BR-B-AC24/DC12-24

Time delay relays are electrical switches controlled by an electronic timer which can be used to switch on or switch off a circuit after a predetermined fixed time delay or a semi-adjustable time hold. They are typically used in applications such as air conditioning, drying or heating, flooring, and ovens, and for medical use. The H5BR-B-AC24/DC12-24 model is a timer relay that can be used in applications such as industrial machinery, manufacturing equipment, and power over Ethernet.

The H5BR timer relay is designed to be used in three different operating modes: as a delay-on timer, a delay-off timer, or an interval timer. In the delay-on timer mode, the timer is activated by a momentary signal and the output relay is energized after a pre-determined time delay. The delay-off timer is responsible for energizing the output relay until a predetermined time delay has passed and then de-energizing it. And, in the interval timer mode, both the initial activation and de-activation of the output relay are determined by a pre-determined time delay.

The structure of the H5BR timer relay consists of a front panel, a printed circuit board, and a main board. The front panel includes a control knob, an LED indicator light, and a start switch. The printed circuit board consists of two sets of contacts that make and break the connection of the control circuit, power supply circuit, and the output circuit. The main board includes several integrated circuits (ICs) and components, such as resistors, diodes, and transistors, which help control the various parameters. Depending on the circumstances, the main board can also include additional components, such as a microprocessor.

The H5BR timer relay works by using a combination of voltage drop, capacitance, and inductive loads to control the current and voltage supplied to the output. When the start switch is actuated, the current and voltage of the output are adjusted slowly in order to increase the current gradually, thus providing a voltage drop in the supply voltage. This voltage drop is then used to determine the time delay for the timer. The capacitor and inductor are used to extract the energy from the voltage drop, which is then used to control the current and voltage of the output. This process is then repeated over and over until the timer switch is released.

The H5BR timer relay is an ideal solution for many applications, including industrial machinery, medical use, and power over Ethernet. It provides accurate, reliable, and safe operation, while its adjustable time delay allows for precise control of the time required for an output process. Furthermore, its modular design makes it easy to install and configure. With its wide range of uses, the H5BR timer relay provides the reliability and flexibility that applications need to be successful.
