7012BA

Time delay relays (TDR) are special electrical mechanisms which are designed to provide various types of continuous control and/or timing components. They use a wide range of existing inputs in order to begin a sequence of events once a particular input or combination of inputs has been established. The most common form of a time delay relay (TDR) is one which uses electronic components, such as integrated circuits, to establish a time delay sequence. The timing components are twofold; time span and ramp up or down rate. The 7012BA is one example of a type of TDR.

The 7012BA is an electronic time delay relay with an adjustable time span and adjustable ramp up or down rates. The relay is triggered by either a normally open (NO) or normally closed (NC) contact. When triggered, the relay will begin a timing cycle using its adjustable time span and adjustable ramp up or down rates. The 7012BA includes two separate timing circuits and both can be adjusted independently.

The 7012BA is used in a variety of different applications such as in industrial control circuits, automotive circuits, and general timing applications. When used in a typical circuit, the 7012BA relay would be connected to an input device such as a switch, limit switch, or pressure switch through a normally open contact or normally closed contact. When the input device is triggered, the relay will begin a timing cycle and activate the output device. The output device could be any type of electromechanical device such as a motor, solenoid, or valve.

The 7012BA relay has several internal electronic components in its circuit. These components control the timing cycle and they include two adjustable timing circuits and two output transistors. The two adjustable timing circuits are adjustable for both time span and ramp up or down rate. They are also adjustable for hysteresis and inrush current.

The adjustable time span allows the user to choose the length of time that the relay will remain active once it is triggered. This can range from a few seconds to several minutes or hours depending on the application. The adjustable ramp up or down rate allows the user to set the desired speed at which the time delay relay will start and stop its cycle.

The output transistors are used to control the output device. They receive signals from the timer circuits and cause the output device to either start or stop, depending on the settings of the timer circuits. The hysteresis and inrush current settings allow the user to adjust the sensitivity of the relay. The hysteresis setting is used to make sure that the relay will remain active once it has been triggered, while the inrush current setting is used to adjust the amount of current needed to activate or deactivate the relay.

The 7012BA time delay relay can be used in applications where a certain amount of time is needed between events. This could be useful in industrial processes, automotive systems, or anywhere else where a precise timing sequence needs to be maintained. Its adjustable time span and ramp up or down rates provide the user with a great degree of flexibility when setting up the timing sequence. With the adjustable hysteresis and inrush current settings, the user can also adjust the sensitivity of the relay.
