These “on-operate” (pull-in) time-delay
solid state relays are housed in a single
industry standard package. AC output
is controlled by a DC input and has an
externally
adjustable
time
delay.
Choices include models with two time-
delay ranges.
Manufactured in Crydom''s ISO 9001
Certified facility for optimum product
performance and reliability.
Series DSD, DLD
Time Delay Relay • 10-50 Amp
