Time delays relays are an indispensable part of automated systems. The PM4HA-H-DC125VW is one of the most popular time delay relays in the market. It has several application fields and working principles.

The PM4HA-H-DC125VW is a heavy-duty time delay relay. It is specifically designed to replace electro-mechanical relays and contactors. It is one of the most efficient time delay relays available and is capable of switching loads of up to 25 amps at 125 volts. It features a robust terminal block and is UL approved.

The PM4HA-H-DC125VW can be used in a variety of applications. It is commonly used in industrial process controls, heating and cooling range controllers, lighting control systems, security systems, and home automation systems. It is capable of switching low current loads such as LED lights and ultra-high brightness lights. It can also be used to control air conditioning and ventilation systems, as well as heated-water systems.

The PM4HA-H-DC125VW is a time delay relay that is capable of controlling time intervals. It can be set to operate at pre-determined times or can be used to trigger an electrical pulse when a certain temperature is reached. It also has a "cold start" mode, which allows it to be activated without a warm-up time.

When used as a time delay relay, the PM4HA-H-DC125VW has three operational modes. The first mode is the hold-on mode, which starts a timed period when activated and continues until it is manually reset. The second mode is the hold-off mode, which continuously maintains a timed period until it is reset. The third mode is the pulse mode, which causes the output to switch on for a pre-determined duration of time after being activated.

The PM4HA-H-DC125VW has several working principles. It can be activated via a digital signal (high/low), a digital signal plus power, an analog voltage, an analog current, or a combination of the above. When activated, it can be configured to provide a single pulse output, a series of pulses, or a continuous output, depending on the application.

The PM4HA-H-DC125VW is an ideal time delay relay for industrial and home automation applications. It is powerful, efficient, UL approved, and capable of switching loads of up to 25 amps at 125 volts. It has several application fields and working principles, making it a versatile and reliable solution.
