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-3V (3 Volt Relay Board) (3 Amp contacts)

Discontinued (use the 'HC' version below)

 This board utilizes the BrightSign 3.3V to power the relay and a logic output (GPIO) to drive the relay.  Normally Open and Normally Closed contacts to TB2. 3 AMP relay contacts.

Links: Specification Sheet          Schematic

 4 Relay Board (12 Volts)

 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-3V (3 Volt Relay Board)

Price Each: $32.00 (USD)

 This board utilizes the BrightSign 3.3V to power the relay and a logic output (GPIO) to drive the relay.  Normally Open contacts to TB2. 3 Amps Contact Rating

 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)  (Coming Mid June)

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!

Non-BrightSign Versions of the Relay boards (Stand Alone)
 (allow 2-3 days extra when ordering these)

These boards have 'input diodes" and Extra Terminal Block for external Power Connections


 Relay-2-12V-SA (12 Volt Relay Board)
Output Type
 2 each 12 volt Relays for Isolated Contacts to control external devices/lamps.  Contact Rating: 5 amps, 120/240AC.  Drive the relays with any HMS 12 volt Output Driver.  New 'AC' version has built in snubber networks to suppress EMI/RFI (potential causes for microprocessor resets and other interference).
