Time delay relays are a key element in the circuit components for electronic, electromechanical, and strong current systems that need to control/activate secondary switches. The H3M-H-AC200/240-D is a type of time delay relay used for applications requiring longer operating times, such as motor start-up/shutdowns, fans, pumps, and other industrial equipment. This article will discuss the application field and the working principle of the H3M-H-AC200/240-D.

Applications

The H3M-H-AC200/240-D is a reliable, robust time delay relay for applications requiring longer operating times up to 10 minutes. This type of relay can be used in a variety of industrial applications, such as motor start-ups and shut downs, fan control, pump control, and other industrial equipment. Motor start-ups often require a time delay to ensure proper functioning of the motor, while fan control and pump control often require a time delay to properly cycle the fan/pump accordingly. The H3M-H-AC200/240-D is therefore suitable for these applications, as it can be programmed with the desired time delay interval.

Working Principle

The H3M-H-AC200/240-D operates on the principle of turning current on and off at specific times. When the relay is energized, the coil of the relay will attract an armature, which in turns causes the contacts to close. This will allow current to flow to the load. When the desired time delay interval has been reached, the relay will de-energize and the armature will release, allowing the contacts to open and thus breaking the current flow. This is the basic operation for the time delay relay.

The H3M-H-AC200/240-D can be programmed according to the desired time delay interval. It is controlled by a timer which is connected to the power supply. When the power is switched on, the timer will start to count down the desired time delay interval. When the time has elapsed, the timer will de-energize the relay, causing the armature to release and the contacts to open, thus breaking the current flow. The timer can be adjusted to control the desired time delay interval and can also be reset to start over again.

The H3M-H-AC200/240-D is suitable for applications requiring longer operating times, up to 10 minutes. This makes it an ideal choice for motor start-ups and shut downs, fan control, and pump control, as it can accurately control the desired time delay interval, allowing the motor/fan/pump to start and operate correctly.

Conclusion

The H3M-H-AC200/240-D is a reliable and robust time delay relay for applications requiring longer operating times up to 10 minutes. This type of relay can be programmed with the desired time delay interval and is therefore suitable for motor start-ups and shut-downs, fan control, and pump control. The H3M-H-AC200/240-D operates on the principle of turning current on and off at specific times, allowing for accurate control of the desired time delay interval.
