Omron H3RN Series Timer Relay, 0.1 s to 10 min Time Range, 24V DC Supply Voltage - H3RN-1-B 24VDC

This timer relay provides versatile time-control functionality for industrial control panels and automation systems. It operates across AC and DC supplies to manage timing sequences and switching tasks, offering a Compact panel-mount format with plug-in terminals for straightforward installation in electrical assemblies.

Features and Benefits:

• SPDT contact delivers single-pole changeover switching capability
• 3A contact rating supports moderate control loads
• 0.1s–10min timing range allows fine short-to-medium intervals
• 250V AC switching voltage handles typical control circuits
• Multifunction timing covers a variety of timing modes
• IP40 enclosure protects internal parts from non-solid objects

Applications

• Suitable for sequencing motors and actuators in automation panels
• Ideal for delay-on and cyclic operations in control cabinets
• Used with relay logic in manufacturing machinery control systems
• Can be used for timing control in electrical test equipment

What supply voltages can it accept for integration in mixed systems?

It accepts 24V AC and a DC range of 12 to 24V, enabling use with both AC control supplies and low-voltage DC control rails.

How is the unit mounted and connected within a control panel?

The device is designed for panel mounting and uses plug-in terminals to simplify wiring and removal for maintenance.

What environmental operating limits should be observed during specification?

The permissible ambient range spans −10°C up to 55°C, which should be considered when locating the unit near heat sources.

What approvals support its use in regulated installations?

It carries recognised approvals including UL, CE, IEC and CSA standards relevant to industrial electrical components.

How is timing adjusted for precise commissioning on-site?

Timing is adjusted using a Swedish Pipe style mechanism to set the required interval within the specified range.
