Overview
The Omron H3BA timer module is a compact solid-state on-delay timer engineered for general industrial automation and control applications. It combines a wide 200/220/240VAC supply voltage range with a 5A @ 250VAC output rating, making it suitable for motor soft-start timing, equipment warm-up delays, and process sequencing in DIN-rail and panel-mount control environments. The H3BA-N series delivers eight flexible operating modes and four selectable time ranges spanning 0.05 seconds to 300 hours.
Key Features
- On-Delay Solid-State Timing – Reliable electronic switching without mechanical components; supports 8 distinct operating modes for flexible timing control
- Wide Voltage Supply Range – 200/220/240VAC (50/60 Hz) accommodates diverse industrial electrical infrastructure
- Four Selectable Time Ranges – 0.05s to 300h enables applications from millisecond-precision to long-duration delays (warm-up, cool-down, cycle timing)
- Compact 1/16 DIN Panel Mount – 45mm × 45mm cutout fits standard control panel layouts; plug-in terminal block simplifies wiring and replacement
- Single Changeover Relay Output (SPDT) – One changeover contact (NO/NC switchable) rated 5A @ 250VAC resistive load
- Industrial Certifications – UL, CSA, CE Marking, and CCC certified for global deployments
