Omron H3FA Series Solid State Timer, 24V DC Supply Voltage, 0.1 to 1s Time Range - H3FA-A DC24
This solid-state timer provides precise time-delay control for DC-powered industrial systems. It is designed for surface mounting and delivers repeatable delayed switching in automation and control circuits, operating across a practical ambient temperature span for factory and equipment-room environments.
Features and Benefits:
• 24 VDC supply enables direct connection to common control rails
• Timing range 0.1 to 1 s allows short, repeatable delays
• SPDT contact arrangement offers changeover switching flexibility
• Two-contact configuration supports simple make/break logic
• Surface-mount format simplifies panel or chassis installation
• Rated for -10 to +55 °C use in typical industrial spaces
• Timing range 0.1 to 1 s allows short, repeatable delays
• SPDT contact arrangement offers changeover switching flexibility
• Two-contact configuration supports simple make/break logic
• Surface-mount format simplifies panel or chassis installation
• Rated for -10 to +55 °C use in typical industrial spaces
Applications
• Suitable for sequential control in conveyor and indexing systems
• Ideal for timing interlocks in machine control cabinets
• Used with DC relay logic in motor starter circuits
• Can be used for short-delay signal conditioning in PLC I/O

What approvals cover electrical safety for use in industrial panels?
The product carries recognised CSA and UL508 approvals intended for control equipment compliance in industrial installations.
How does the contact configuration affect wiring options?
The single-pole changeover contact allows a common Terminal to switch between two outputs, enabling either normally-open or normally-closed wiring schemes without extra relays.
What environmental conditions limit deployment?
Ambient temperature must remain within -10 to +55 °C to maintain specified operating behaviour and timing accuracy.
How many discrete switching elements are available for control circuits?
There are two contacts provided, enabling Basic dual-circuit switching or redundant signal paths as required by a control design.
