About the Digital Inputs and Outputs
All general purpose inputs and outputs are optically isolated. They operate in the 12–24 VDC range, and
can be wired to be either sinking or sourcing.
can be wired to be either sinking or sourcing.
Inputs
For sourcing inputs, connect the input common pin(s) to the 12–24V line of the power supply. The input
devices are then connected to the common ground line of the power supply at one end, and individual
input pins at the other.
For sinking inputs, connect the input common pin(s) to the common ground line of the power supply. The
input devices are then connected to the 12–24V line of the power supply at one end, and individual input
pins at the other.

For sourcing outputs, connect the common collector (pin #29) to the 12–24V line of the power supply.
The output devices are then connected to the common ground line of the power supply at one end, and
individual sourcing output pins at the other.
For sinking outputs, connect the common emitter (pin #11) to the common ground line of the power
supply. The output devices are then connected to the 12–24V line of the power supply at one end, and
individual sinking output pins at the other.

Do not mix topologies for outputs. They are all either sinking or
sourcing. If the common emitter is used, the common collector should
not be connected and vice versa.

Newer models of the Geo Brick LV were introduced in October of
2012 and can be recognized by the 5-pin terminal block STO
