TFI Series Compact Timing Relays

Weidmuller’s TFI series timing relay portfolio includes multifunction, star-delta switch, clock generator, on-delay, and off-delay devices. These compact timing relays cover the most critical applications in building and factory automation. The timing functions and time ranges are configured utilizing rotary switches on the front of the devices.

In automation technology, timing relays are used to compensate for errors caused by high clock rates. Timing relays extend short pulses so that downstream control components can reliably detect them.

The TFI series devices comply in design and function with the international standard for timing relays according to EN 61812. All timing relays have cULus listing for the North American market.
