Time Delay Relays

Time delay relays are a type of electrical switch that operates when a preset time interval has passed. The relay can be programmed to operate either with a specified delay upon application of power, or with a specified delay upon removal of power. This type of relay is commonly used when an application requires multiple parts of a system to operate after a given delay.

PM4HF11R-S-DC12VW application field and working principle

The PM4HF11R-S-DC12VW is a 12VDC time delay relay with 4-pin DIN connections. This relay is often used in industrial and commercial applications such as fire alarm systems, HVAC control systems, access control systems, and security systems. It can be used to control triggering of alarms, activating relays, and switching contactors for motor controls.

The PM4HF11R-S-DC12VW is designed to operate simply and efficiently. It works by sensing a voltage change after a preset time. When power is applied to the relay, an LED indicator will light up. After the preset time has been reached, the contacts within the relay will open or close, based on the user’s choice. The relay can be programmed to operate with a preset time from 0.3 seconds to 30 minutes.

The PM4HF11R-S-DC12VW is a very versatile time delay relay and can be used in many different applications. It is easy to use and can be changed quickly if needed. With its multiple settings and robust design, this time delay relay is a great option for controlling multiple parts of a system.
