 		 #74655 - RE: Relay interface problem
Responding to: ???'s previous message
dear kasyap
presently i am working with relays and mc with uln 2003
inbetween successfuly. USE sugarcubePCB relays as they have high coil resistance and draw less current as compared to older body mounting relays. USE a reverse diode on coils of the relays . use logic 0 or gnd. from 2003 to operate the relays and apply vcc directly at the other end of relay.
good luck
ankas
