Mar 10, 2021

Weidmuller’s compact TFI-Series relays for building and factory automation are designed for universal applications in factory and building automation and fulfill many functions in industrial environments. Timing relays are used in automation technology in order to compensate for errors caused by high clock rates. Short pulses are extended and are reliably identified by downstream control components.The TFI-Series consists of five different devices covering the most important applications in building and factory automation. Four of these carry out individual functions: clock generator (pause and pulse start), star-delta switch, switch-on delay and off-delay with control input. There is also a multifunctional version with seven different timing functions. The timing functions and time ranges can be easily configured using a rotary switch fitted on the front. All of the devices meet the international standards according to EN 61812 and have UL approval for the North American market.
