Datasheet

Omron H3YN Series Solid State Timer, 0.1m inch to 10h Time Range, 24V AC Supply Voltage - H3YN-21-B AC24

This solid-state timer provides timed control for industrial switching and sequencing tasks in automation environments. Designed for DIN-rail mounting, it accepts AC and DC supplies and offers multifunction timing capability across a wide dwell range, enabling precise delays and intervals for control panels and machinery. The unit accommodates push-in wiring and a double-pole changeover contact arrangement suitable for common industrial control schemes.

Features and Benefits:

• 0.1min-10h timing range allows precise long and short delays
• 24VAC and 125VDC supply compatibility supports mixed systems
• DPDT contact configuration provides two independent switching circuits
• 5A contact rating enables direct control of moderate loads
• Push-in terminals speed installation and wiring changes
• IP40 protection rating suits protected indoor control cabinets

Applications

• Suitable for sequence timing in conveyor control systems
• Ideal for delay functions in motor starter circuits
• Used for interval timing in process automation panels
• Can be used for timed control in HVAC actuator interfaces
• Suitable for lamp and signalling timing in machine safety circuits

What mounting method is required for installation?

It is intended for DIN-rail fitting, allowing secure attachment to standard 35mm rails used in control enclosures.

Which approvals indicate compatibility with industrial standards?

It carries CE marking and meets a range of international standards including EN 61812-1, UL508, CSA C22.2 No.14, IEC 60664-1, CCC and Lloyd's approvals for use in regulated applications.

What are the expected operating temperature limits?

The device functions within an ambient range from -10°C up to a maximum of 55°C for reliable performance in typical indoor industrial environments.

How many functions does the timer offer and how does that help integration?

It provides multiple timing functions, enabling selection of different delay modes for flexible integration into varied control logic without additional external circuitry.
