TFI-SERIES
Compact timing relays for building and factory automation
Timing relays fulfil many functions in industrial environments. In automation
technology, they are used to compensate for errors caused by excessive cycle
rates. Among other things, short pulses are extended so that they can be reliably
detected by downstream control components.
Our 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, 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.
Your special advantages:
• Recessed setting potentiometers and status indication via LED
• Suitable for control voltages from 12/24 - 240 V UC and
ambient temperatures from -25 °C to +60 °C
• Available in installation design and compact industrial design
• CE-compliant and UL-certified for international use
