Omron DIN Rail Timer Relay, 4-Contact, DPDT Switch, 24-240 V AC/DC, 0.1 s to 1200 h, 1-Function H3DT

Omron H3DT Series DIN Rail Timer Relay, model H3DT-A2 24-240VAC/DC, is designed for reliable timing control in industrial automation systems. It features a slim DIN Rail mount, ideal for efficient control panel layouts. This timer relay supports a single ON Delay function, allowing precise delay timing adjustable via a dial that ranges from 0.1 seconds up to 1200 hours.

Its robust contact configuration consists of 4 contacts arranged as a DPDT switch, offering versatility in switching operations. The device accommodates a wide power supply range from 24 V AC to 240 V AC/DC, ensuring compatibility with varied control systems. Push-in terminals enable quick, secure wiring connections for ease of installation.

Constructed for industrial environments, the H3DT relay meets multiple stringent standards including UL 508 and cULus certifications, along with electromagnetic compatibility compliance per EN 61000 series standards. It has an IP20 and IP30 rating, protecting against ingress of solid objects and limited moisture, suitable for indoor control cabinet use.

The timer relay operates reliably over a temperature range of -20°C to 60°C, making it well-suited for industrial and commercial automation processes requiring accurate timing delays. Its compact size, measuring 100mm high, 90mm wide, and 17.5mm deep, allows integration into space-constrained panels. With a contact rating of 5A and switching voltage capability of up to 250V, the H3DT is capable of handling moderate load control.
