7014PA Industrial Controls

Time Delay Relays

Time Delay Relays are electronic devices which require a given amount of time to be triggered and actioned, such as to turn on an appliance, open or close a circuit, or sound an alarm. They are used for various purposes, such as to prevent an overload on a system or to signal that a switch is open or closed. The 7014PA application field and working principle are discussed here.

Application Field

The 7014PA time delay relay can be used in a number of different applications. These include controlling the start and stop of motors, controlling the operation of pumps, monitoring the status of switches, and detecting the opening or closing of safety circuits. It can also be used in process control applications, such as controlling the operation of valves.

Working Principle

The 7014PA time delay relay works by monitoring the current within a circuit, and then delaying the output when a certain current level is reached. This is known as ‘sensing’. When the current reaches the predetermined limit, the device will delay the output for a predetermined length of time. This is known as ‘timing’. The output is then activated after the timer expires.

The device has a number of different modes that can be used for different timing purposes. It has a ‘one shot’ mode, which will delay the output for a single timing cycle. It also has a ‘cyclical’ mode, which will delay the output for multiple timing cycles. It can also be set to a ‘pulse on demand’ mode, which will delay the output for a predetermined number of cycles. Finally, there is a ‘pause’ mode, which will delay the output for a certain period of time before resuming the cycle.

The 7014PA is a versatile device, allowing it to be used for a variety of applications and controlling equipment. It is a reliable and durable piece of equipment, making it a popular choice for industrial and commercial operations.
