A unique feature of the LVK204-25
is the ability to control relays*
and other external devices using one
of six General Purpose Outputs. Each can source up to 20mA of current at five volts when on or sink
10mA 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.

In addition to the six general purpose outputs the LVK204-25
offers an Optional Dallas One-Wire bridge,
to allow for an additional thirty two one-wire devices to be connected to the display. This header can be
populated with a Tyco 173979 connector at an added cost by custom order only.
