Product Description

The OMRON AH3-NB timer relay, a key component of the AH3 series time relays, offers precise timing control with 1 input and 1 output channel, enabling direct integration with up to 5 external modules. Designed for industrial automation and machinery systems, it operates across a wide voltage range of 24-240V AC/DC and withstands temperatures from -10°C to +55°C. Supporting NBIoT communication for remote monitoring, this relay ensures reliable performance in energy management, HVAC, and process control applications. Its compact design enhances space efficiency, while a durable mechanical construction ensures long-term stability. Notable for its ±0.1% timing accuracy and DIN-rail mounting compatibility, the AH3-NB excels in scenarios requiring repeatable cycle control, though its lack of programmable memory limits complex timing sequences.
