1. Automated Conveyor Staging Control
Sequential motor starting and pausing are required on multi-stage conveyor lines to prevent product jams and reduce electrical inrush current across the control system.
Problem SolvedOperating on a standard 24 VDC industrial control voltage, the H3YN-4-B's ON-delay and interval modes sequence the staggered start of conveyor segments. The 0.1s to 10m range covers short transfer delays, while the 4PDT output allows simultaneous signaling of downstream drives and upstream stop gates.

2. Pump Lubrication Cycle Management
Heavy industrial machinery requires periodic, brief pulses of lubricating oil without relying on complex PLC logic for basic timing loops.
Problem SolvedUtilizing the Flicker-OFF Start or Flicker-ON Start modes, this solid-state timer precisely cycles lubrication pumps. Its 10-minute maximum range manages the intervals between lube cycles, and its 3A, 250 VAC rated 4PDT relay can directly drive multiple small solenoid valves or indicators.

3. Local Fault Annunciation Circuitry
Control panels require localized visual and auditory alarm sequencing (such as flashing beacons and horns) upon a system fault, necessitating an independent hardware fallback separate from the main PLC.
Problem SolvedThe timer's Flicker-ON Start mode flashes warning beacons intermittently. With compact dimensions (21.5mm width) and an IP40 rating, it integrates easily into densely packed local alarm panels, while the 14-pin plug-in design ensures rapid replacement in mission-critical circuits.
