A unique feature of the LK204-7T-1U 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.
