Its delay range spans 1 minute to 1 year, set via up/down digit keys — so it covers everything from short process pauses to seasonal cycling without needing a separate long-range timer. The 3A at 250VAC contact rating handles pilot-duty loads, small contactors, or signal-level switching; it is not sized for motor starting or high-inrush loads. Supply is 100-240VAC, which means it works directly on common line voltages without a separate control transformer. ## Deployment context Panel-mount form factor with screw terminals — integrates into control panels via a standard cutout, not DIN rail. The screw-terminal termination style suits field wiring in industrial enclosures where quick disconnect is not required. Timing initiation is via input voltage, so the relay starts its delay cycle when power is applied.","metaTitle":"H5S-YB4-X Programmable Timer Relay, 1 Min–1 Year, 3A 250VAC","metaDescription":"H5S-YB4-X mechanical relay timer, SPST-NO x 4, programmable 1 min to 1 year delay. 100-240VAC supply, screw terminals.
