A unique feature of the GLK24064-25/GLT24064 is the ability to control relays
* and other external
devices using either one or 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.
*Note: If connecting a relay, be sure that it is fully clamped using a diode and capacitor in order to absorb any
electro-motive force (EMF) which will be generated.
