BS-4Opto (4 Isolated Inputs/Buttons)

for BrightSign units w/GPIO

DB15 Connector with 4Opto couplers    

BS-4Opto Input (Button) board

Features:

• small footprint (1.7 x 1.7 inches)
• Mounts directly to the DB15 connector (captive hardware provided) on the BrightSign
• 4 Opto-coupler inputs (some call them solid state relays).  For use with 12 and 24 volts DC remote activation devices.

This board solves the need for using a relay to convert a control signal of 12 or 24 volts DC to a switch closure.  The BrightSign only works with 'switch closure' to 0Volts to activate the GPIO inputs.  The opto-couplers convert the 12 or 24 volt input to a 'switch closure' to operate the GPIO inputs (BTN0-BTN3)

There is an 8 pin terminal block marked with +V and 0V for each of the 4 inputs.  The 4 inputs are labeled 0-3 (this corresponds to Btn0-Btn3 of the BrightSign.  This board is utilized when another device applies 12 volts or 24 volts to turn on a remote device (the BrightSign).
