Why Choose the Finder 80.11.0.240.0000T ON-Delay Timer Relay?
The Finder 80.11.0.240.0000T is a railway-oriented ON-delay timer relay designed for controlled switching, delayed activation and electrical sequencing in railway and industrial automation applications. Part of the Finder 80 Series, this modular timer features a wide 24–240 V AC/DC supply range, an adjustable timing range from 0.1 seconds to 24 hours and a single changeover (SPDT / 1 CO) output rated at 16 A.
Unlike multifunction timers, the Finder 80.11.0.240.0000T provides a dedicated ON-delay (AI) timing function. When the supply voltage is applied, the timer begins its preset delay, and the output relay changes state once the selected time has elapsed. Removing the supply resets the timer, making it suitable for delayed equipment activation, contactor sequencing and auxiliary control circuits.
The T suffix identifies the railway-oriented variant, specified for applications involving railway fire behaviour and mechanical environmental requirements, including EN 45545-2 and EN 61373. Its compact 17.5 mm-wide housing, screw terminal connections, LED indication and 35 mm DIN rail mounting make it practical for installation in railway electrical cabinets and industrial control panels.

Reliable ON-Delay Timing for Railway and Industrial Control Systems
Electrical control systems frequently require equipment to start only after a defined delay. The Finder 80.11.0.240.0000T provides this functionality through its dedicated AI ON-delay operating mode. When supply voltage is applied, the timing sequence begins while the output remains in its initial state. Once the preset delay expires, the changeover contact transfers, allowing the connected control circuit to operate.
When the supply is removed, the relay returns to its initial state and the timing cycle resets. This makes the device suitable for delayed contactor energisation, staged equipment activation, sequential control and auxiliary switching where a repeatable power-on delay is required.
The timer's 24–240 V AC/DC operating range allows it to be used across different control supply arrangements, while its 16 A changeover contact provides switching capability for appropriately rated loads. For inductive loads, contactors or motor-control equipment, the applicable utilisation category and manufacturer's switching limits should be checked before installation.
The railway-oriented T version is intended for applications where fire behaviour, shock and vibration requirements are important selection criteria. Compliance with a railway equipment specification must be assessed at system level, including the relevant installation conditions and any additional project-specific approvals.
