Omron Series DIN Rail Timer Relay, 1 to 120 Seconds Time Range, 2-Contact SPDT Switch, 100-120 V AC, 240 V DC Power-Off H3DT

Omron H3DT Series DIN Rail Timer Relay (Model: H3DT) provides reliable and adjustable time-delay functionality for industrial automation and control applications. It supports a timing range from 1 to 120 seconds, enabling flexible delay settings essential for precise control processes.

The relay includes two contacts arranged as a single-pole double-throw (SPDT) switch rated for 5A current, suitable for moderate load switching needs. It accepts an AC supply of 100-120 V and a DC supply of 240 V, offering versatility for different control panel power configurations.

Featuring screw terminals and DIN Rail mounting, it ensures secure electrical connections and rapid installation in compact panels. The dial timing adjustment facilitates easy onsite calibration for operational flexibility. Engineered to perform within an ambient temperature range of -20°C to 60°C, it withstands harsh industrial environments.

Compliance with international standards including UL 508, CSA C22.2 No. 14, DNV GL, EN 61812-1, and IEC 60664-1 with a dielectric strength of 4 kV/2 reinforces its electrical safety and reliability. The IP30/IP20 rating protects the device from solid particulate ingress in control setups.

This timer relay is ideal for sequencing control in automated assembly systems, time-delay functions in motor starter circuits, control-logic timing in HVAC systems, and staged lighting or signaling control. Its compact profile suits marine or offshore control panels requiring robust, space-saving relays.

This relay features a 2-contact SPDT switching configuration rated for moderate 5A load handling. It operates on 100-120 V AC and 240 V DC power supplies with screw terminal connections for secure wiring. DIN Rail mounting ensures fast and reliable panel installation in control systems.

Adjustable dial timing allows quick on-site calibration for accurate delay settings. Designed to operate in temperatures from -20°C to 60°C, suited for various industrial environments. Complies with multiple industry standards including UL 508, CSA C22.2 No. 14, DNV GL, EN 61812-1, and IEC 60664-1 with a robust IP30/IP20 rating.
