 		 #75020 - RE: Relay interface problem
Responding to: ???'s previous message
I am using 6V relay (60mA) to switch 24V DC 5W Solenoids ( it looked like 6 when I last wrote the solenoid specs )

I am using a separate 5V supply for ULN since by eval board supply may not be able to power to all relays. I have joined the ground of eval board and that of ULN and 74HC04 which is powered by the second power supply

I am attaching the description of my circuit with this post for enabling you to see what I am doing



Thank you

Deepak
