Omron H3YN Series DIN Track Solid State Timer, 4-Contact, 125 V dc 125V ac, 0.1 s to 10 min, Multifunction-Function,

Omron H3YN Series Solid State Timer, 0.1 s-10 m in Time Range, 125V DC Supply Voltage - H3YN-2-B DC125

This solid-state timer provides precise timing control for industrial automation and electrical systems, delivering selectable delays across a wide span for process sequencing. It is designed for DIN-rail mounting in control cabinets and offers AC/DC supply compatibility suitable for typical control voltages in machinery and panel installations.

Features and Benefits:

• Time range 0.1s to 10 min enables fine delay adjustment
  DPDT 5 A contacts support dual-circuit switching needs
  AC/DC 125V supply permits versatile power sourcing
  Push-in terminals reduce wiring time and improve connection security
  IP40 enclosure rating suits protected indoor control panels
  Multifunction capability consolidates various timing modes

Applications

• Suitable for sequencing motors and actuators in automation lines
  Ideal for timed control of industrial lighting and signalling circuits
  Used with relay logic for interlock and safety delay functions
  Can be used for timed start/stop of pumps in process equipment
  Used for delay control in conveyor and material-handling systems

What contact performance can I expect for switching loads?

The unit provides four contacts arranged as DPDT with a rated current of 5 A per contact for switching typical control and small power loads.

Which approvals indicate suitability for industrial installations?

It carries multiple international approvals covering safety and electrical standards including CE, UL 508, IEC 60664-1 and CSA C22.2 No. 14.

What ambient temperatures will it tolerate during operation?

The device is specified to operate between -10°C and 55°C, allowing use in standard indoor industrial environments.

How is the device secured in the control enclosure?

It mounts directly onto DIN-rail hardware, providing a standardised method of installation within control cabinets.

What dielectric or switching voltage limits are relevant for system design?

The switching voltage rating is 250V AC, which should be considered when selecting loads and coordinating insulation clearances.
