DELAY-ON-BREAK TIMING RELAYS
KRDB, KSDB, TDUB SERIES
DESCRIPTION
The KRDB Series is a compact time delay relay measuring
only 2 in. (50.8 mm) square. Its microcontroller timing circuit
provides excellent repeat accuracy and stability. The KSDB
Series is designed for general purpose commercial and industrial
applications where a small, cost effective, reliable solid-state timer
is required. This series is designed for popular AC and DC voltage.
The TDUB Series combines digital timing circuitry with universal
voltage operation and offers DIP switch selectable time delays
ranging from 0.1 seconds to 102.3 minutes in three ranges.
