⚙️ Working Principle:
The AH3-3 Timer Relay works by energizing its internal relay after a preset time delay. When power is applied, the internal circuit starts counting based on the selected time range. Once the delay period is reached, the relay output switches ON or OFF depending on configuration.
This allows automation systems to control processes sequentially, delay machine start-ups, or avoid power surges by staggering activations.
