Time Delay Relays

Time Delay Relays (TDRs) are a type of relay that delays the activation of its contacts for a predetermined amount of time. TDRs can be used to control various loads and protect circuits from overloads. TDRs can also be used to control analog and digital signals, and provide feedback, enabling the relay to respond to various types of stimulus.

The 7012QC TDR is a dual channel time delay relay designed to provide reliable activation and deactivation of loads at preset intervals. It features both an ON and OFF channel, allowing it to be used for various applications. The 7012QC can control loads from 0.1VAC to 300VAC, and it is designed to withstand current levels up to 16A. It is CE certified for electrical safety, and features UL and TUV approvals, making it suitable for use in worldwide markets.

7012QC Application Field

The 7012QC TDR can be used in a variety of applications. It is typically used in industrial automation, motor control, safety equipment, renewable energy applications, and intelligent building applications. It can be used to control circuit breakers, relays, contactors, and other loads. It is also used to control analog and digital inputs, and can be used to monitor and control the temperature, humidity, and other environmental conditions.

The 7012QC is also used for lighting control. When coupled with a dimmer, the 7012QC can be used to adjust the intensity of a light to desired levels. It can also be used to control the street lights, thus allowing for energy savings. It is often used to control the operation of pumps, motors and valves, providing higher efficiency and greater control over the operations.

7012QC Working Principle

The working of the 7012QC TDR is quite simple. It uses a delay timer module to delay the activation or deactivation of the load. The delay timer can be programmed in a number of ways, such as continuous cycling, hold-up delay, delay-on-make, and delay-on-break. The delay can be set in increments of 0.1-second to 99 hours, allowing for precise control of the load.

The 7012QC also has a control input loop, which is used to change the delay time during operation. This input can be connected to a sensor, another relay, or any other input device that is capable of sensing a change in the environment. The sensed input is then used to adjust the delay time, allowing for dynamic control of the load.

In addition to the control loop, the 7012QC can also be configured to trigger other relays. This is done by connecting the output of the 7012QC to the input of another relay. The output of the 7012QC can also be used to trigger a variety of other loads, allowing it to be used in a wide variety of applications.

Conclusion

The 7012QC TDR is a versatile time delay relay that can be used in a variety of applications. It can be used to activate and deactivate loads, adjust the intensity of lights, and trigger other relays. It features a delay timer module that can be programmed in a variety of ways, allowing for precise control of the load. The 7012QC can also be configured with an input loop, allowing for dynamic control of the load. In short, the 7012QC TDR is a reliable and versatile relay.
