Omron H3CR Series DIN Rail Timer Relay, 24 to 48 V, 0.05 s to 30 h, 2-Function, SPST Switch Configuration

This timer relay is a Compact control device designed for timed switching tasks within industrial control systems. It accepts a broad range of supply voltages and offers selectable timing to manage delays and sequencing in automation, electrical and mechanical installations. The unit mounts on standard DIN rails and connects via plug‑in terminals for straightforward panel integration.

• Supply accepts 12–48V AC or 24–48V DC enabling flexible power sources
• Time adjustment from 0.05s to 30h allowing fine delay tuning
• Single‑pole single‑throw contact rated 5A supporting modest load switching
• Multifunction capability providing two timing function selections
• IP20 and IP30 protection levels suited to enclosed panel environments
• Operating range from -10°C to 55°C for varied ambient conditions

• Suitable for sequencing motors and conveyors in factory automation
• Ideal for delay control in control panels and relay logic racks
• Used with solenoids and contactors requiring timed energisation
• Can be used for timed lighting and signalling in industrial facilities
• Used for process timing in packaging and material handling stations

It clips onto DIN rail sections, enabling fast installation and removal via its plug‑in Terminal interface.

Two distinct timing functions are available, allowing different delay behaviours to be chosen for common control scenarios.

It is designed to operate reliably between -10°C and 55°C for indoor industrial environments.

Wiring is achieved through plug‑in terminals that simplify replacement and reduce downtime during maintenance.
