Omron H3FA Solid-state Timers
The Omron H3FA Solid-state Timer is a compact DIP model designed for PC board integration, providing both contact and solid-state output options for flexible control applications. This timer supports selectable time ranges from seconds to minutes, making it ideal for use in embedded control circuits, timing modules, and automation boards requiring reliable delay functions. With a 24-pin IC socket mountable design, the H3FA ensures easy installation and serviceability on printed circuit boards. Built to deliver stable performance even when cleaned while mounted, the H3FA combines precision timing with robust construction for industrial PC board applications. This product is manufactured by Omron and categorized under Omron Solid-state Timer.
The Omron H3FA Series Solid-state Timer offers versatile timing functionality with four selectable time ranges to suit a variety of control requirements. Models suffixed with “-A” cover timing from 1 second to 10 minutes, while “-B” variants extend from 6 seconds to 60 minutes, enabling broad application use across control panels and PCB-level timing tasks. The H3FA’s design allows mounting on a standard 24-pin IC socket or direct PC board soldering, and its sealed construction supports board cleaning without removal. Available with either conventional contact outputs (SPST-NO + SPST-NC) or solid-state outputs capable of switching DC loads, this timer adapts to both mechanical relay and electronic control interfaces. Its compact footprint (19.5 × 36.9 × 17.75 mm) and ability to mount on a 1-inch pitch rack make the H3FA suitable for dense circuit designs in automation, control boards, and timing logic applications.
