Time Delay Relays are devices commonly used to regulate the operation of industrial equipment and to signal the presence or absence of an electrical switch in a control circuit. The type of time delay relay used in the 1472981-6 application field is a Solid-State Split-Phase Programmed Time Delay Relay. The time delay relays, so named because they can provide “fixed” or “delay-on” timing, are used in many automation tasks. For example, they are used to regulate the operation of a conveyer system, to reduce power surges or to signal the presence or absence of an electrical switch in a control system.

A Solid-State Split-Phase Programmed Time Delay Relay (1472981-6) is designed to time from 0.10 to 10.0 seconds as a standard unit. This relay can also be modified to go beyond the 10.0 second timing range by using a longer timing cycle or an extended timing range, depending on the customer’s needs. It is a normally closed and pulse-activated relay that can be used in many applications, including industrial automation, temperature control, lifesaving pulse-time delays and others. Its operation works similarly to a mechanical-timed relay, in that the customer specifies the interval of time. The main feature of this type of relay is that it operates by solid-state components, meaning it uses transistors and integrated circuits instead of contacts.

This type of relay works by using a timer circuit that is triggered upon application of a control signal. The relay can be set up to run in either a “delay on” mode, in which the output is enabled after the preset-time has elapsed, or in a “delay off” mode, in which the output is enabled before the preset-time has elapsed. The output can be set up to perform one of three actions when the preset time has expired: energizing, de-energizing, or continuously cycling for a period of time.

The internal components of the 1472981-6 relay start the timing cycle when a momentary pulse is applied to the control terminals. This pulse will start the internal timer, allowing the output to be either energized (for a normally closed contact) or de-energized (for a normally open contact) after the set timing cycle. The pulse can either close or open the output contacts, depending on the relay’s setting. The unit is also equipped with a fine-adjustment potentiometer with a range of 0.10-10.0 seconds for variable timing control. This allows the user to adjust the timing cycle, depending on the application.

The 1472981-6 solid-state time delay relay has three LED status indicators, which indicate when the output is On, Off and timing respectively. The relay is UL listed, CSA approved and VDE compliant, making it suitable for many industrial and commercial applications. It is an ideal solution for applications that require precise timing cycles, such as motor and pump start/stop control, production line automation and process control.
