3.3V Relay Boards for GPIO
Note: The BrightSigns cannot directly drive relays as they require more current than the GPIO can drive!


 Relay1-DR-3VHC (3 Volt Relay Board) (10 Amp contacts)

Price Each: $18.00 (USD)

 This board utilizes the BrightSign 3.3V to power the relay and a logic output (GPIO) to control the relay.  Normally Open and Normally Closed contacts to TB2. 10 AMP relay contacts.

Links: Specification Sheet          Schematic

 4 Relay Board (12 Volts)

 Relay2-DR-3VHC (3 Volt Relay Board)

Price Each: $36.00 (USD)

 This board utilizes the BrightSign 3.3V to power the relay and a logic output (GPIO) to control the relay.  Normally Open contacts to TB2.  10 Amps Contact rating!

 4 Relay Board (12 Volts)
Microprocessor prevents 'pulse of relay' on power-up

 Relay2-DR-uP (3 Volt Relay Board)

Price Each: $38.00 (USD)

This board utilizes the BrightSign 3.3V to power the relay and a logic output (GPIO) to a processor that drives the relays.  Normally Open contacts to terminal blocks TB1 & TB2

Note: BrightAuthor does not allow for preset of the GPIO states when setting the GPIO outputs.  If you need the relays To 'not close' momentarily on power up, then order this relay board instead of the relay board shown above!
