The ULN2065B Switch Board controls much higher voltages and currents.

The board consists of 2 ULN2065B Quad Darlington Switches, and a blue LED indicator setup to indicate which channels are currently active.
ULN2065B Switch Board devices contain four NPN Darlington switches delivering up to 1.5 A with a specified minimum breakdown of 50 V and a sustaining voltage of 35 V measured at 100 mA.
The channels output connections are by screw terminals that will accept cables 0.5 – 2mm. The connection between the I/O24 module and the Combo board is via a 30 cm IDC connection cable provided with the board.

  • 2 x ULN2065B (80V 1.5A Quad Darlington switches)
  • Indication Blue LED’s for channel status
  • Screw Terminal Blocks for outputs
  • Wire gauge: 22-14 AWG
  • Easy connection by 10-way box header to suit standard IDC connector for connection to the I/O port
  • 72mm Standard width for DIN Rail Modules
  • Dimensions – 2.6 X 2.8 X 1 inches (65 X 72 X 25.4mm)

Note: you must take care not to exceed the maximum specifications of the
ULN2065. For more information in regards to the ULN2065B please, refer to
the datasheet
