This circuit board allows you to use 8 bits (TTL) of digital
output (available on almost all low-end DAC boards) tocontrol eight other devices or components that draw up to 10
Amps (relay, lamp, etc.) each. The device can either be anAC or DC device. This board uses a relay that has both
Normally Open (NO) and Normally Closed (NC) contacts.A very nice small board with lots of uses.
Example Hook-Up:
Below is a diagram on how you might hook this board up to your DAC device.

Miscellaneous Information:
The relays on this circuit board are rated for 10 amps of current. The circuit board has not been tested atthe maximum rated current. I have routinely used it to switch motors and solenoids that drew around 3
amps each for extended periods of time and have not seen any problems with the circuit handling thoseloads and expect it to perform well at higher currents. EMF protection is provided by the diodes internal

to the transistor array chip. Also, the circuit traces for the relays have been beefed-up with extrasolder for higher current handling. If you are switching high current solenoids or relays and are still
getting feed-back, I also sell a board that will prevent that. Contact me for more details.
