Time Delay Relays (TDRs) have long been used in industrial applications to automate tasks. The PM4HA-H-DC125V is one such relay that is designed for use in applications that require precise timing and control. This powerful relay features both AC and DC voltage inputs and can be programmed to provide various timing functions. In this article, we will look at the application fields for this time delay relay and its underlying working principles.

Application Field for PM4HA-H-DC125V

The PM4HA-H-DC125V time delay relay is used in a wide range of applications including controlling machine processes, managing system startups, providing timed operation for pumps, opening and closing of traffic lights, delay of alarms or alerts, and providing timed watering of agricultural fields. It is best suited for industrial applications that require precise timing and control. It can be used for both AC and DC voltage applications with a current range of 6A. It also features a built-in protection latch for additional safety.

Working Principle

To understand the working principle of the PM4HA-H-DC125V time delay relay, we must first discuss its components and their respective functions. The time delay relay consists of a time delay circuit, relay driver, and a relay switch. When a voltage is applied to the time delay circuit, the relay driver becomes active and sends an electrical signal to the relay switch. The relay switch then either opens or closes depending on the setting of the time delay. This allows the relay to automatically control the desired process with precise timing.

The PM4HA-H-DC125V time delay relay is adjustable from 0.1 seconds to 10 minutes depending on the set time delay values. There is also a manual override function that allows the user to manually control the relay without relying on the set time delay. This makes the PM4HA-H-DC125V time delay relay a versatile and reliable tool for industrial applications.

Conclusion

The PM4HA-H-DC125V time delay relay is a powerful and reliable relay designed for industrial applications that require precise timing and control. It features a wide range of applications from controlling machine processes, providing timed watering of agricultural fields, providing timed operation of pumps, and more. It also features both AC and DC voltage inputs and adjustable time delays of up to 10 minutes. With its powerful and reliable design, the PM4HA-H-DC125V time delay relay is an ideal choice for industrial applications.
