SSAC KRPD Series Data Sheet

KRPD SeriesTimer

Connection:

L1 N/L2

V = Voltage
C = Common, Transfer Contact
NC = Normally Closed
NO = Normally Open
S1 = Initiate Switch
UTL = Untimed Load

A knob is supplied for adjustable units

or R

terminals for external adjust. The

T

untimed load is optional. S1 is not used

for some functions.

The KRPD Series is a factory programmed time
delay relay available with 1 of 12 standard dual
functions. The time delays can be factory xed,
onboard or externally adjustable or a combination
of xed 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.

See Appendix B, page 165, Figure 1 for dimensional

drawing.
