Time Delay Relays are common electronic components used in automated systems, and they come in all shapes and sizes to fit different needs. The CHB-38-70003 Time Delay Relay is a particularly versatile component that can be used in a variety of different applications. This article will explain the uses of the CHB-38-70003 Time Delay Relay and its working principle.

Applications

The CHB-38-70003 is extremely versatile when it comes to its applications, making it popular among engineers and technicians. The relay is used primarily in industrial applications, but also has non-industrial uses. Here are some of the common applications for the CHB-38-70003 Time Delay Relay:

• Control of mechanical operations in manufacturing.
• Elimination of relay chatter in control systems.
• Indication of long period machine start-up or shutdown.
• Control of repetitive operations in production lines.
• Time delay alarms.
• Start and stop sequencing of motor components.

The CHB-38-70003 Time Delay Relay is also ozone-resistant, making it ideal for use in manufacturing processes where ozone poses a risk. The Time Delay Relay can also be used in safety systems, as any failure will be detected quickly and the system shut down.

Working Principle

The CHB-38-70003 Time Delay Relay works by using a timing circuit to control an output. The timing circuit takes a signal from an input line and then uses this to control the output. Basically, the timing circuit is used in order to activate the output after a certain period of time. The period of time can be adjusted as required by the engineer or technician.

In order to adjust the delay period, the user needs to adjust two parameters: the pre-delay time and the post-delay time. The pre-delay time is the amount of time that the time delay relay waits before activating the output and the post-delay time is the amount of time that the relay waits before deactivating the output. Both of these parameters can be adjusted to match the desired delay period.

For example, if the desired delay period is 10 seconds, then the pre-delay time would need to be set to 10 seconds and the post-delay time would need to be set to 0 seconds. This means that the output will be activated 10 seconds after the input signal is received and deactivated immediately afterwards.

The CHB-38-70003 Time Delay Relay also has a slow-opening feature, which is designed to reduce the stress on the output components. This feature means that when the output is activated, it is gradually brought up to its full voltage. This ensures that the output components are not exposed to suddenvoltage spikes, which could lead to damage.

The CHB-38-70003 Time Delay Relay is a great choice for a variety of applications, ranging from control systems to time delay alarms. The relay is ozone-resistant and has a slow-opening feature to reduce the stress on output components. In addition, the delay period is easy to adjust with the pre-delay and post-delay settings.
