Why Choose the Finder 13.01.0.024.0000T Electronic Impulse Relay?
The Finder 13.01.0.024.0000T is a 24 V AC/DC electronic impulse and monostable relay specifically designed for railway applications and industrial electrical control systems. Part of the Finder 13 Series, this modular relay combines impulse-operated switching with conventional monostable control in a compact, DIN rail-mounted device.
Featuring one changeover contact (1 CO / SPDT) rated at 16 A, the Finder 13.01.0.024.0000T provides a versatile switching solution for lighting, signalling, auxiliary control and electrical automation circuits. Its dual operating modes allow engineers to select between latching impulse operation and monostable switching according to the requirements of the installation.
The T suffix identifies the railway application version, distinguishing this model from the standard Finder 13.01.0.024.0000 relay. With a 35 mm module width, IP20 protection and compatibility with 35 mm DIN rail mounting, it is suitable for professional electrical installations where compact construction, flexible control and reliable operation are important.

Understanding Impulse and Monostable Relay Operation
The Finder 13.01.0.024.0000T combines two different switching functions within one electronic relay, allowing the same device to support different control arrangements.
In impulse or bistable mode, the relay changes its output state in response to a control impulse. A momentary push-button command can switch the output from one state to the other, with a subsequent impulse reversing the state. This is particularly useful where an electrical load must be controlled using momentary push buttons rather than a maintained switch.
For example, a lighting circuit may be operated from multiple control positions using suitably connected push buttons. Each valid impulse changes the relay output state, allowing the connected lighting circuit to be switched without requiring a conventional multiway switching arrangement.
In monostable mode, the output follows the applied control command. The relay operates while the appropriate control signal is present and returns to its normal state when that signal is removed.
This makes the Finder 13.01.0.024.0000T suitable for applications requiring either impulse-based switching or maintained-signal control. The appropriate input terminals and wiring arrangement must be selected according to the manufacturer's installation diagram.
The electronic design also offers quieter operation than traditional mechanically actuated impulse relays, which can be beneficial in enclosed electrical installations and applications where switching noise should be minimised.
Special Railway Version for Transport Electrical Systems
The Finder 13.01.0.024.0000T is specifically identified as a railway application version of the 13.01 electronic relay.
Railway electrical systems often incorporate auxiliary switching circuits for lighting, signalling, control and onboard equipment functions. Such systems require components to be selected with particular attention to their electrical supply arrangements, environmental conditions and applicable railway equipment requirements.
The 24 V AC/DC supply option makes this model relevant to railway control systems using compatible low-voltage supplies. Its modular construction allows installation within suitable electrical distribution and control cabinets.
The T suffix is an important part of the manufacturer reference. It should not be omitted when specifying or purchasing a replacement for a railway installation, as the standard version and the railway-specific version are distinct product references.
Although the Finder 13.01.0.024.0000T is marketed for railway applications, suitability for a particular rolling stock, trackside or infrastructure project must be confirmed against the current Finder technical documentation and the project's applicable railway standards. The railway designation alone should not be treated as evidence of every possible railway certification.
The Finder 13.01.0.024.0000T incorporates one changeover contact rated at 16 A. This SPDT arrangement provides a common terminal, a normally closed contact and a normally open contact.
When the relay changes state, the common connection transfers between the two contact paths. This allows the device to be incorporated into control circuits requiring either normally open or normally closed operation.
The relay's maximum switching voltage is 400 V AC, while the permissible switching current depends on the load category and the operating conditions. The stated 16 A contact rating must not be assumed to apply unchanged to every type of electrical load.
Inductive loads, motors, transformers, LED drivers and other loads with significant inrush current may require additional consideration or a lower permissible switching current. The complete load characteristics should be checked against the manufacturer's applicable contact ratings before installation.
The silver tin oxide (AgSnO) contacts provide a contact material commonly used in industrial switching applications. The cadmium-free composition also supports component selection where material restrictions are relevant.
Compact 35 mm DIN Rail Installation
The Finder 13.01.0.024.0000T is designed for mounting on a standard 35 mm DIN rail to EN 60715. Its 35 mm overall width allows it to be incorporated into modular electrical distribution boards and industrial control cabinets.
The relay uses screw terminal connections, allowing the supply, command inputs and output circuit to be wired according to the appropriate Finder installation diagram.
Its IP20 protection rating provides basic protection against access to hazardous parts with a finger and ingress of larger solid objects, but it does not provide protection against water. The relay must therefore be installed within an enclosure appropriate to the operating environment.
The specified operating temperature range of -10 to +60 °C should be considered during panel design. Where multiple electrical devices are installed close together, enclosure temperature and ventilation must be assessed to ensure that the relay operates within its permitted conditions.
All installation, testing and maintenance work should be carried out by competent personnel with the electrical supply safely isolated. The manufacturer's wiring instructions must be followed, particularly when selecting the impulse or monostable operating arrangement.
