Please read and understand this catalog before purchasing the products.
Please consult your OMRON representative if you have any questions or
comments. Refer to Warranty and Application Considerations (page 20),
and Safety Precautions (page 16).
Solid-state Timer with Valuable Multiple-time
Ranges and Multiple-operating Modes
• Handles a wide range of applications through six operating
modes.
• With H3BA-N8H models, the output type can be switched
between time-limit DPDT and time-limit SPDT + instantaneous
SPDT using a selector.
• Setting rings (order separately) to enable consistent settings
and to limit the setting range.
• Panel Covers (order separately) to enable various panel
designs.
• Conforms to LR and approved by UL and CSA.

Questions and answers
Is it possible to have an automatic reset or do you have to have a switch to reset timer?
The Omron H3BA-N timer requires a switch for resetting. It uses a start/reset input (e.g., pin No. 2) to reset the timer, which operates when a transistor or relay is turned ON. There is no mention of an automatic reset feature.
