Time Delay Relays
Dedicated - Delay-on-Make
KRPS SERIES
Description
The KRPS Series is a factory programmed time delay relay
available with 1 of 15 functions and measures only 2 inches
square. The KRPS offers a wide range of fixed, onboard, or
externally adjustable time delays. The 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 KRPS Series is a cost effective approach for OEM
applications that require small size, isolation, accuracy, and long
life. Special time ranges and functions are available.
