General Purpose Outputs
A unique feature of the GLK240128-25/GLT240128 is the ability to control
devices using one of six General Purpose Outputs. Each can source up to 10mA of current at five volts
when on or sink 20mA at zero volts when off. The two row, fourteen pin header can be interfaced to a
number of female connectors to provide control to any peripheral devices required.
