Omron H3RN-2-B AC24 Реле времени

Omron H3RN Series Solid State Timer, 0.1s-10m in Time Range, 24V AC Supply Voltage - H3RN-2-B 24VAC

This solid-state timer is a Compact timing relay designed for control-panel mounting to manage timed switching in industrial automation and electrical systems. It operates from low-voltage supplies and offers multifunction timing across a wide interval, enabling precise control of circuits where repeatable delays and reliable switching behaviour are required.

Features and Benefits:

• Time range 0.1s-10min provides versatile delay selection for processes
  Supports 24V AC or 12-24V DC supply for flexible installation
  DPST contact configuration allows independent switching of two circuits
  Contact rating 3A enables switching of moderate loads up to 250V AC
  Plug-in Terminal type permits fast replacement and simplified wiring
  IP40 enclosure rating suits protected panel environments

Applications

• Suitable for sequence control in automated machinery
  Ideal for timed activation of control valves and actuators
  Used with relay logic for interlock and safety timing functions
  Can be used for delay-on/interval timing in conveyor systems
  Suitable for replacing electromechanical timers in retrofits

What Terminal arrangement is offered for mounting and serviceability?

The unit uses a plug-in Terminal Interface that simplifies removal and replacement without rewiring the panel.

How tolerant is the device to ambient temperatures during operation?

It is rated to operate between -10°C and 55°C to accommodate typical industrial indoor environments.

Which electrical isolation or standards does the device meet for safety considerations?

It conforms to recognised electrical and safety standards including EN and IEC requirements and carries relevant approvals for industrial control equipment.

What switching capability does it provide for mains-connected loads?

The contacts are rated for switching up to 250V AC at a continuous current of 3A, suitable for many control and signalling loads.
