80.41.0.240.0000T Finder Modular timer Offdelay DC 24/240V

Why Choose the Finder 80.41.0.240.0000T Off-Delay Timer Relay?

The Finder 80.41.0.240.0000T is a professional multivoltage off-delay timer relay designed for industrial automation, railway applications and electrical control systems requiring accurate, adjustable delayed switching. Part of the Finder 80 Series, this compact modular timer provides a 0.1 s to 24 h adjustable timing range, a single changeover relay output and a dedicated control-signal input for initiating the off-delay function.

Featuring a universal 24–240 V AC/DC supply voltage, the Finder 80.41.0.240.0000T is suitable for integration into a wide variety of industrial control installations. Its off-delay with control signal operating function allows the output relay to remain energised for a selected period after the control signal is removed, making it particularly useful for delayed shutdown, ventilation overrun, sequential equipment stopping and controlled machinery operation.

The relay incorporates one single-pole double-throw (SPDT) changeover contact, providing both normally open and normally closed switching options. Its adjustable timing system offers six selectable time scales, allowing the required delay to be configured using accessible front-mounted adjustment controls.

Designed for demanding environments, the 80.41T variant is associated with railway-related requirements including EN 45545-2, EN 61373 and EN 50155. The timer features screw terminals, LED status indication, a compact 17.5 mm housing width and standard 35 mm DIN rail mounting, making it suitable for space-efficient installation inside industrial and railway electrical control cabinets.

Reliable Off-Delay Timing for Industrial and Railway Control Systems

Industrial machinery and railway electrical equipment frequently require controlled shutdown sequences rather than immediate disconnection of auxiliary equipment. Fans, pumps, ventilation systems and other electrical loads may need to continue operating for a predetermined period after a control command is removed. The Finder 80.41.0.240.0000T provides this functionality through its dedicated off-delay timing operation.

Unlike an on-delay timer, which delays output activation, the Finder 80.41T operates using an off-delay with control signal function. When the supply is present and the appropriate control signal is applied, the output responds according to the timer's operating logic. When the control signal is removed, the selected timing interval begins, and the relay output changes state after the programmed delay.

The adjustable timing range of 0.1 s to 24 h provides considerable flexibility. Short delays can be used for control sequencing, while longer periods are suitable for ventilation overrun, delayed equipment shutdown and auxiliary processes. Six selectable time scales allow the required delay to be configured without programming software.

The 24–240 V AC/DC universal supply makes the relay suitable for different industrial electrical control architectures. This flexibility can reduce the number of voltage-specific timer variants required across a maintenance inventory, while simplifying the selection of a replacement unit for compatible applications.

The timer provides a single SPDT changeover output, enabling a suitable electrical circuit to be switched using either the normally open or normally closed contact. The connected load must remain within the applicable output contact ratings, and inductive loads may require appropriate suppression or interface equipment.

The 80.41T variant is particularly relevant to railway electrical installations. Its design addresses requirements associated with fire behaviour of materials, mechanical vibration and shock, and railway environmental conditions. The specified operating temperature range of −25 to +55 °C supports operation in suitably protected industrial and transport control environments.

Installation is straightforward using the 35 mm DIN rail mounting system and screw terminals. The compact 17.5 mm housing minimises panel space requirements, while the front-mounted timing controls and LED indication support efficient commissioning, adjustment and maintenance.

Important operating consideration: The Finder 80.41.0.240.0000T is a control-signal-operated off-delay timer, not a true power-off-delay timer. Its timing function requires the appropriate supply conditions to be maintained. Applications requiring timing to continue after removal of the timer's own power supply should use a suitable true power-off-delay device, such as a compatible Finder 80.61T model.
