Time Delay Relays are devices used in a variety of industrial applications, such as controlling circuits, extending the cycle time of machines, or providing additional safety features for safety-critical systems. The CUB-51-70120 is a particularly versatile type of Time Delay Relay, designed to meet the needs of a wide range of industries.

General Characteristic of CUB-51-70120

The CUB-51-70120 Time Delay Relay is 18 mm wide and 12 mm high with a long-life, rugged plastic enclosure. It has two miniature switches, each with a 10A maximum contact current, and operates at up to 250 VAC without requiring external power. The memory function saves the last programmed value in case of a power outage. Its simple operation and small footprint make it ideal for a wide range of applications, including industrial controls, medical applications, consumer products, and automotive applications.

Application Field of CUB-51-70120

The CUB-51-70120 is designed for applications requiring reliable timing functions. This device is ideal for applications such as machine cycle timing, electrical equipment monitoring, process control/monitoring, and motor control. It is also well-suited for alarms, temperature controls, timer functions, and time-delay-on-break applications. The device also has the ability to be programmed for a wide range of time delay intervals, from 100 ms to 100 h.

The CUB-51-70120 can be programmed for both single-shot and continuous timing cycles, as well as an external reset control link. It also features three time range settings, allowing the user to select the most appropriate value for the application. The two output switch contacts can control other devices such as valves, pumps, alarms, and motors.

Working Principle of CUB-51-70120

The CUB-51-70120 employs an electrical timer circuit to control its outputs. When the device is activated by applying power, an internal capacitor starts to charge until it reaches a certain voltage threshold, at which point the contacts switch on. The contacts then remain on until the voltage level has been reduced again, at which point the contacts switch off. This process repeats itself each time the device is activated, providing reliable time delay cycling.

The CUB-51-70120 Time Delay Relay also features adjustable timing ranges, allowing the user to vary the time delay interval from 100 ms to 100 h, depending on the specific application. This adjustable range allows the user to control the time delay cycle more accurately, ensuring that the output contacts are switched on only for the required time interval. This precision can be especially important when dealing with safety-critical systems.

Conclusion

The CUB-51-70120 is a cost-effective and reliable Time Delay Relay that can be used in a variety of applications. Its small size, long-life plastic enclosure, and adjustable time interval make it an ideal choice for industrial, medical, consumer, and automotive applications. With its memory function, it can be programmed for both single-shot and continuous-timing cycles, and its adjustable time interval offers precision control over the timing cycle.
