Omron Panel Timer Relay, Multifunction, SPDT, 5-Contact, 12V DC/AC, 0.1 s - 10 min, Plug-In, IP30/IP20 H3RN

The Omron H3RN-1-B 12VDC Panel Timer Relay is a robust industrial timing device engineered for precise control and automation. Designed to handle both 12V DC and 12V AC input supplies, it delivers versatile timing functions with adjustable intervals from 0.1 seconds up to 10 minutes, supporting a wide range of sequencing, delay, and timing tasks required in control panels, manufacturing lines, and building automation.

This timer relay features a Single-Pole Double-Throw (SPDT) contact configuration, allowing reliable switching for single-pole changeover applications. The five-contact arrangement enables the relay to interface with multiple circuits, providing ample flexibility in complex industrial installations.

Its multifunction timing capability supports diverse delay modes essential for process automation, such as timed activation of indicators, interlock sequences, and cyclical delays in conveyor systems and automated test rigs. Integration is straightforward, as the relay is designed for convenient panel mounting with plug-in terminals that facilitate quick replacement and servicing.

The compact body, measuring 31.2mm in height, 47.2mm in width, and 12.8mm in length, ensures efficient utilization of panel real estate, making it ideal for space-limited electrical enclosures. The relay sustains a contact current rating up to 3A, suitable for controlling actuators, lamps, buzzers, and low-power devices.

Engineered for industrial durability, the Omron H3RN-1-B 12VDC timer relay operates reliably within ambient temperatures from -10°C to 55°C. The housing provides internal IP30 protection and IP20 for accessible parts, making it best suited for protected panel interiors, avoiding exposure to outdoor environments.

This relay is RoHS compliant and stands out for easy installation, repeatable accuracy, and robust electrical performance. Its applications span across industrial automation, HVAC control, machinery sequencing, assembly lines, and laboratory test setups where timed electrical switching is essential.
