A unique feature of the LK202-25/VK202-25
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.

In addition to the six general purpose outputs the LK202-25/VK202-25
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.
