83.11.0.240.0000T Finder timer Ondelay (AI) DC 24/240V

Why Choose the Finder 83.11.0.240.0000T ON-Delay Timer Relay?

The Finder 83.11.0.240.0000T is a railway-oriented, single-function ON-delay timer relay designed for delayed switching, electrical sequencing and industrial automation applications. Part of the Finder 83 Series, this modular timer features a universal 24–240 V AC/DC supply range, an adjustable timing range from 0.05 seconds to 10 days and a 16 A single changeover relay output.

Featuring the AI (ON-delay) timing function, the Finder 83.11.0.240.0000T provides controlled output activation after a preset time interval. When the supply voltage is applied, the timer begins counting down the selected delay. Once the preset period has elapsed, the changeover output operates, allowing connected control equipment to be activated in a controlled sequence.

The T suffix identifies the railway-oriented version of the Finder 83.11 timer, making it particularly relevant to electrical equipment used in railway applications. Its 22.5 mm-wide housing, screw terminal connections, DIN rail mounting and adjustable timing controls provide a practical solution for railway electrical cabinets, industrial machinery and automation control panels.

Extended ON-Delay Timing for Railway and Industrial Automation

Electrical control systems often require a defined delay between the application of a control supply and the activation of connected equipment. The Finder 83.11.0.240.0000T provides this functionality through its dedicated AI ON-delay timing mode, allowing engineers to introduce a controlled waiting period before a switching operation takes place.

When the supply voltage is applied, the timer starts its preset timing interval while the output remains in its initial state. Once the selected delay expires, the 16 A changeover relay output operates. Removing the supply resets the timer, allowing the sequence to begin again when power is restored.

The adjustable timing range from 0.05 seconds to 10 days makes this relay particularly versatile for applications requiring either very short activation delays or extended waiting periods. Its 24–240 V AC/DC supply compatibility allows the same timer type to be considered across different industrial control voltage arrangements.

As a railway-oriented T variant, the device is also relevant to railway auxiliary control systems where project specifications require equipment selected for railway service. The suitability of the timer for a particular installation, including any applicable railway environmental or approval requirements, should be confirmed against Finder's current technical documentation.

For motor-control applications, the timer can be used to delay the energisation of suitably rated contactor coils or auxiliary relays. The switching capacity must be assessed against the actual load type, utilisation category and electrical characteristics rather than the nominal contact current alone.

Typical Applications

• Railway vehicle auxiliary electrical control systems.

• Industrial machinery start-up sequencing.
• Motor-control circuits requiring delayed activation.
• Electrical distribution and control panels.
• Ventilation and auxiliary equipment timing.
• Automated doors, gates and access-control equipment.
• Material handling and conveying systems.
• Long-duration timing and delayed switching applications.
