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 9002
Certified facility for optimum product
performance and reliability.
Series DSD, DLD
Time Delay Relay 10-50 Amp
