KRPD SERIES
Description
The KRPD Series is a factory programmed time delay relay
available with 1 of 12 standard dual functions. The time delays
can be factory fixed, onboard or externally adjustable or a
combination of fixed and adjustable. The SPDT output relay
contacts offer a full 10A rating with complete isolation. Its
microcontroller timing circuit provides excellent repeat accuracy
and stability. Encapsulation protects against shock, vibration,
and humidity. The KRPD Series is a cost effective approach for
OEM applications that require small size, isolation, accuracy and
long life.
