2.4 General Purpose Outputs
General Purpose Output, which can provide up to 20 mA of current and +5Vdc from the positive side of
the GPO. This is limited by a 240 ohm resistor which is located to the above right of the GPOs as pictured
below in
a relay) and has an internal resistance of its own greater than 250 ohms, then the 240 ohm resistor may be
removed and replaced with a Jumper.
2.5 Dallas 1-Wire Bridge
allow for an aditional thirty two 1-wire devices to be connected to the display. Please note the the display
normally does not come with the Dallas 1-wire bridge. It will have to be ordered as a custom. Please talk to
your sales representative if you would like this option. See Section 8 on page 34.

A unique feature of the LK202-25 is the ability to control relays and other external devices using a
In addition to the six general purpose outputs the LK202-25 offers an optional Dallas 1-wire bridge, to

. If the device, which is being driven by a GPO, requires a relatively high current (such as
WARNING 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.
