Eight Selectable Timing Functions

The Finder 86.00.0.240.0000T provides eight selectable timing modes, allowing the same timer module to perform several different control tasks. These functions include supply-triggered delays, fixed intervals, repetitive switching and externally controlled timing operations.

AI – On-Delay

The AI function delays operation of the associated relay after the timer supply is applied. Once the selected interval has elapsed, the output relay changes state according to the applicable timing diagram.

This function is useful for delayed equipment activation, sequential start-up arrangements and control circuits requiring a waiting period before operation.

DI – Interval

The DI function provides a timed operating interval following supply energisation. The associated relay operates for the selected duration before returning to its initial state.

Typical applications include timed equipment activation, temporary control outputs and defined-duration switching operations.

SW – Symmetrical Flasher, Starting ON

The SW function provides repetitive ON/OFF switching with equal operating and pause periods. The cycle begins with the output energised.

This function is suitable for periodic switching, repeating control sequences and compatible signalling applications.

BE – Off-Delay with Control Signal

The BE function provides delayed release of the associated relay after a control signal changes state. It is useful when equipment must remain active for a defined period after an external command has ended.

Potential applications include delayed ventilation shutdown and controlled equipment run-on sequences.

CE – On-Delay and Off-Delay with Control Signal

The CE function provides timing associated with both the application and removal of a control signal. This enables delayed activation and delayed deactivation within one timing mode.

It can be useful for filtering brief control commands and managing equipment start and stop sequences.

DE – Interval with Control Signal ON

The DE function initiates a timed interval in response to a control signal being applied. The resulting output sequence follows the selected interval and the manufacturer's timing diagram.

This mode is suitable for externally triggered timed operations.

EE – Interval with Control Signal OFF

The EE function initiates an interval associated with removal of the control signal. It is useful where a defined output period is required after a control command ends.

FE – Interval with Control Signal ON and OFF

The FE function provides interval timing associated with both application and removal of a control signal. It offers additional flexibility for externally initiated timing sequences.

Important: The exact output transitions, retriggering behaviour and reset conditions for all eight functions must be checked against Finder's official timing diagrams before commissioning.

How the Finder 86.00T Plug-In Timer Module Works

The Finder 86.00.0.240.0000T is an electronic timing module rather than a complete electromechanical relay. It is designed to be installed in a compatible relay and socket assembly, where it controls the timing of an associated relay's operation.

When the appropriate supply and control conditions are present, the timer module executes the selected timing function. At the required point in the sequence, it controls the associated relay, allowing the relay contacts to switch the connected electrical circuit.

This modular arrangement offers an important advantage: the timing module does not determine the number of switching contacts or their electrical current rating. Those characteristics depend on the compatible relay fitted to the assembly.

For railway applications, Finder documents the 86.00T module with a 56.34T relay and 96.04.7 socket. This arrangement provides a complete timed relay assembly when the specified compatible components are correctly installed.

The modular design also supports maintenance and component replacement. However, the correct timer, relay and socket combination must always be verified before installation or substitution.

Railway-Specific T Version for Rolling Stock Applications

The Finder 86.00.0.240.0000T is intended for railway applications and is associated with environmental requirements for electronic equipment installed on rolling stock.

Its railway design references the following standards:

• EN 50155: Electronic equipment used on railway rolling stock, including relevant environmental operating requirements. The module is associated with temperature class T1.
• EN 61373: Shock and vibration testing for railway equipment, with Category 1 Class B classification.
• EN 45545-2 + A1:2016: Railway vehicle fire protection requirements relating to the fire and smoke behaviour of materials and components.

These characteristics make the timer module suitable for consideration in rolling stock electrical control cabinets, auxiliary equipment systems and railway automation assemblies.

Compliance of the individual timer module does not automatically establish compliance of the complete electrical assembly. The associated relay, socket, wiring, enclosure and operating conditions must also meet the requirements of the railway project.

Installation and Compatible Relay Assemblies

The Finder 86.00.0.240.0000T is designed for plug-in installation with a suitable Finder relay and socket. It is not intended to be wired or mounted as a standalone DIN rail timer relay.

For the railway-specific 86.00T version, Finder identifies the following compatible arrangement:

• Timer module: Finder 86.00.0.240.0000T
• Associated relay: Finder 56.34T
• Associated socket: Finder 96.04.7
• Resulting assembly: Multifunction timed relay arrangement with output characteristics determined by the selected relay

The timer module's compact 54 × 38 × 11.8 mm dimensions allow it to be incorporated into the compatible socket arrangement without requiring a separate conventional timer housing.

Its 12–240 V AC/DC operating range allows the module to be used with several common railway and industrial control voltages, subject to the manufacturer's detailed supply requirements.

All installation work should be undertaken by competent personnel. The correct relay and socket combination, electrical supply, wiring arrangement and selected timing function must be verified against the manufacturer's current documentation.

• Railway rolling stock auxiliary control systems.
• Train electrical equipment cabinets.
• Railway ventilation and environmental control systems.
• Timed control of auxiliary railway equipment.
• Railway electrical switching sequences.
• Industrial machinery control panels.
