Omron H3YN-21-B AC24 Реле времени

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?
