In a typical DC electric braking circuit, which component supplies power to the braking relay?

In a typical DC electric braking circuit, the component that supplies power to the braking relay is the NOTO contact. This contact functions as an essential part of ensuring that power is appropriately routed to the braking relay when a braking command is initiated. The term NOTO stands for normally open, which indicates that in its resting state, the contact is open, preventing current from flowing. When the braking command is activated, the NOTO contact closes to allow current to flow through, energizing the relay coil and engaging the braking mechanism.

Understanding the role of the NOTO contact is critical, as it directly influences the operation of the entire braking system by controlling when power is supplied. This is crucial for the safe and effective application of brakes in DC drives, ensuring that the braking action can be executed promptly when needed.
