Omron H3RN Series Front Solid State Timer, 2-Contact, 24 V dc 24V ac, 0.1 min to 10 h, Multifunction-Function, DPST-NO

Omron H3RN Series Solid State Timer, 24V Supply Voltage, 0.1min to 10h Time Range - H3RN-21 24VDC

This solid-state timer is a Compact timing device designed for control-panel and automation use, providing selectable delay functions for AC or DC control circuits. It is intended for front-panel mounting and interfaces via a socket connection, offering multifunction timing across a wide selectable interval to manage sequence control and timing tasks in industrial systems.

Features and Benefits:

• Time range 0.1 min to 10 h delivers flexible delay settings
  24V AC/DC supply allows integration with common control voltages
  DPST-NO contact arrangement enables switching of two circuits
  3 A contact rating suits moderate load switching requirements
  Multifunction selection supports varied timing modes
  IP40 enclosure rating protects against solid intrusion in panels

Applications

• Suitable for sequence timing in factory automation control panels
  Ideal for delay control in electrical distribution relay racks
  Used with PLCs for pre-programmed time-dependent operations
  Can be used for interlocking delays in mechanical process lines

What Terminal style is used to connect the device into a control system?

Connections are MADE via a socket-mounted Terminal arrangement to simplify replacement and wiring.

What environmental temperature range will it operate within?

It functions reliably between -10°C and 55°C for typical indoor industrial environments.

How many independent switching elements are provided and what configuration are they?

There are two switching elements configured as double-pole single-throw normally open contacts to control two circuits simultaneously.

Which approvals indicate suitability for international installations?

The unit meets recognised EN standards and holds CSA and UR approvals for cross-border regulatory acceptance.
