They are ideal for operating control desks, pantographs, door control, and can also be used in electronic messaging systems.

55T Series General Purpose Relays. These 4 CO 7A plug-in relays are used to manage train air conditioning systems, exterior and interior lights, on-board appliances and infotainment panels.

56T Series Miniature Power Relays. Available in 2 or 4 contact 12 A versions, either plug-in or with Faston 187 connections, these relays can be used to control pantographs and signal boxes as well as exterior and interior lights, and power sockets within carriages.

86T Series Timer Modules. Finder offers both a multi-function, multi-voltage version as well as a dual-function, multi-voltage version of this plug-in timer module. Both feature a wide nominal voltage range and a time scale from 0.05 s  to 100 h. These specifications make them suitable for door control and train appliance management.

80T Series Modular Timers. These timers are available in multi-function, multi-voltage or single-function, multi-voltage versions. They boast six time scales, from 0.1 s to 24 h and a high input/output isolation. In the railway sector they are used in the shunting operations of rolling stock, for door control, and for the management of electronic messaging systems and infotainment panels.

The 70T Series Line Monitoring Relays are electronic phase loss and rotation monitoring relays for three-phase applications. They are based on positive safety logic, i.e. the make contact opens if the relay detects an error. Available in 1 CO 6 A and 2 CO 8A versions, they can be used for workshop power sockets and for the control of train air conditioning systems.
