Product Description

The Omron H3CR-A-301 AC24-48/DC12-48 is a reliable DIN rail timer relay engineered for meticulous control in automation panels, lighting circuits, HVAC systems, machine operations, and industrial timing applications. Combining compact design with multifunction timing capabilities, it delivers flexibility and convenience for systems requiring scheduled operations or delay circuit interventions.

Its wide voltage compatibility - accepting 12 to 48V DC, and 24/48V AC - allows seamless integration across diverse control systems. The relay’s adjustable time delay spans from instantaneous 0.1 seconds to exceptionally long 600 hours, enabling both rapid and extended timing requirements. The DPDT double contact configuration provides robust switching for controlling multiple circuits and complex process sequences.

The timer relay operates reliably within ambient temperatures from -10°C to +55°C, making it suitable for operation in demanding environments such as industrial automation lines, commercial lighting, and HVAC timer circuits. Installation is straightforward, thanks to the plug-in crimp terminal connectors and standardized DIN rail mounting. The compact body, measuring 48mm wide, 48mm deep, and 81.6mm high, conserves panel space while fitting easily into crowded enclosure layouts.

Time intervals are set with an intuitive knob adjustment mechanism, and the relay supports ON Delay mode essential for sequential starts, delay circuits, and event-driven automation. Its IP40 rating ensures basic ingress protection while international certifications - CSA, EN61812-1, UL, CE, CCC, NK, IEC60664-1, LR - attest to its global reliability and compliance.

Omron’s H3CR Series timer relays, including this exact model, are frequently used in sequential logic control, safety delay functions, lighting operation automation, and motor protection timing. Typical applications include machinery panel sequences, HVAC unit cycling, industrial conveyor delays, and lighting timer systems.
