Omron H3YN Series DIN Track Solid State Timer, 4-Contact, 125 V dc 200V ac, 230 V ac, 0.1 min to 10 h,

Omron H3YN Series Solid State Timer, 200V AC Supply Voltage, 0.1min to 10h Time Range - H3YN-21-B AC200-230

This solid-state timer is a DIN-rail mounted timing relay designed for control and sequencing tasks in industrial automation. It operates on AC supply voltages and offers multifunction timing over a wide range, enabling repeatable time-delay behaviours for switching circuits in electrical and mechanical systems while fitting Compact installations.

Features and Benefits:

• Multifunction timing range 0.1 min-10 h for flexible sequencing
  DPDT 5 A contacts for switching multiple circuits simultaneously
  AC200-230V supply supports common industrial mains
  Push-in terminals for fast, secure wiring connections
  250V AC switching voltage to handle typical load voltages
  IP40 rated enclosure for protection in control panels

Applications

• Suitable for motor start delay and interlock sequences
  Ideal for conveyor stop/start timing in production lines
  Used for lighting control and timed power distribution
  Can be used for process control where repeatable delays are required

What contact arrangement does it provide and how does that help?

It uses a double-pole double-throw contact set, allowing independent switching of two circuits from a single timing function, useful for controlling both power and signal lines concurrently.

Which mounting method is supported for panel integration?

It mounts on a DIN rail, enabling straightforward installation in standard control enclosures and quick replacement without panel modifications.

What temperature limits apply during operation?

The device is rated to operate between -10 °C and 55 °C, suitable for typical indoor industrial environments.

Are there approvals relevant to industrial electrical systems?

It complies with multiple standards including UL 508, EN 61812-1, CSA C22.2 No. 14, IEC 60664-1, CE, Lloyd’s and CCC, aligning it with regulated equipment requirements.

What supply options exist for DC-operated systems?

A 125V DC supply rating is provided for installations requiring DC timing control.
