How does a no volt relay work

WebRELAY OPERATION When no voltage is applied to pin 1, there is no current flow through the coil. No current means no magnetic field is developed, and the switch is open. When voltage is supplied to pin 1, current flow though the coil creates the magnetic field needed to close the switch allowing continuity between pins 2 and 4. UNDERSTANDING RELAYS WebOct 20, 2024 · 1) Control wiring: Consider it as a DC relay. 2) Work control: Although the control voltage is connected, whether it plays a control role is determined by the timer on the panel. 3) Function understanding: It is a switch,single-pole double-throw, with an active point, just like the active arm of a common knife switch.
