Omron H3YN Series Timer Relay, 12V Supply Voltage, 0.1min to 10h Time Range - H3YN-21-B DC12

This timer relay is a Compact electromechanical timing device designed for panel installation in industrial control systems. It provides selectable delay functions across a broad time span and accepts low-voltage supplies for straightforward integration into automation and electrical assemblies.

Features and Benefits:

• DPDT contacts rated at 5A enabling versatile switching capacity
• Time range adjustable from 0.1min to 10h for precise delays
• Accepts 12V AC and 12V DC to suit mixed supply environments
• Push-in terminals for Rapid wiring and maintenance
• Switching capability up to 250V AC for common control circuits
• Conforms to multiple international standards for system compatibility

Applications

• Suitable for sequencing motors and pumps in control panels
• Ideal for delay control in conveyor and material-handling systems
• Used with industrial timers for phased lighting and signalling
• Can be used for interlock timing in machinery safety circuits

What environmental temperatures can it withstand during operation?

It operates reliably between -10°C and 55°C, allowing use in many indoor industrial settings.

How is the unit mounted within an enclosure?

It is designed for panel mounting to fit directly into control panels and switchboards.

What level of ingress protection does it provide against dust and contact?

The enclosure meets IP40, offering protection against solid objects larger than 1mm but not against water.

How many independent contacts are available for wiring?

There are four changeover contact poles configured as double-pole double-throw to support multiple circuit functions.
