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 directly above the positive pin 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.
Matrix Orbital
A unique feature of the VK202-25 is the ability to control relays and other external devices using a
figure 23
. 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.
