Power relays, especially those above 2 amperes, are an integral part of many systems. LY2 DC125 is one of the most commonly used power relays falling in the above category. Before looking into the application field and working principle of this power relay, let’s get familiar with its characteristics and construction.

LY2 DC125 is a double-pole double-throw (DPDT) relay rated up to 125V and 24A. It has two sets of common, normally open (NO) and normally closed (NC) contacts. When energized, the relay changes its state and the NO/NC change. This relay measures 50x36x25mm and can handle 2.2KW of power at 220 Vac. It is a DIN rail mountable relay and thus, can be easily synchronized with other relays in a system. Compared to other relays in the category, it offers better contact operations, considering its smaller physical size.

Application field –

One of the most common areas of application of the LY2 DC125 is for controlling lighting circuits. The model’s common, NO/NC contact setup provides for excellent flexibility in designing and controlling the lighting circuit. This relay is also a perfect pick for any residential or commercial HVAC system and is among the most demanded relays among HVAC contractors. Because of its higher current ratings and DIN rail mountable features, it is suitable for complex industrial systems such as for controlling motors.

Working principle –

The working of the LY2 DC125 is quite straightforward. It has an electromagnet which is housed inside the relay. This electromagnet has two windings connected in series. When current passes through the two windings, it produces a magnetic field and causes the armature to move back and forth between the set of NO/NC contacts. The commands to energize or de-energize the relay are provided through the coil. When the coil is energized, it pulls in the armature, which then makes contact with the NC and interrupts the circuit. When the coil is de-energized, the armature returns back to the common contacts and provides for the continuity of the circuit.

Overall, the application field and working principle of LY2 DC125 relay make it a wise choice for a lot of applications and HVAC systems. For this reason, this power relay has made it to the top of the list in the power relays market above 2 amperes.
