Omron H3CR Series DIN Rail Timer Relay, 100 V, 0.1 s to 600 h, Multifunction-Function, SPST Switch Configuration

This timer relay provides adjustable timing functions for control panels and automation systems, delivering selectable delays and multifunction control in industrial environments. It accepts wide-range AC supplies and a DC option, fits into DIN-rail assemblies via a plug-in terminal, and is suited to applications requiring configurable time delays from fractions of a second up to many hours.

• Multifunction timing supports diverse control scenarios and sequencing
• Time range from 0.1 s to 600 h enables short pulses to long delays
• SPST contact rated 5A handles common control-circuit loads
• Accepts 100–240V AC and 100V DC supply for flexible installation
• Plug-in DIN-rail mounting simplifies replacement and maintenance
• IP30 and IP20 construction suits protected control-panel environments

• Suitable for conveyor start/stop sequencing in manufacturing lines
• Ideal for lighting delay control in machine enclosures
• Used for pump cycling where long dwell times are required
• Can be used for interlock timing in automated testing rigs
• Used with PLCs for external hardware timed functions

The device uses plug-in terminals designed for DIN-rail mounting to allow quick connection and straightforward removal without panel rewiring.

The unit is specified to operate between -10 °C and 55 °C, so it should be located where ambient temperatures remain within that range.

A single-pole single-throw contact provides one switching output rated at 5 A, appropriate for typical relay-driven loads and signalling circuits.

The product complies with RoHS requirements, indicating restricted use of certain hazardous substances in its construction.
