2.4 General Purpose Output
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 as pictured below in
driven by a GPO, requires a relatively high current (such as 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 LCD0821 is the ability to control relays and other external devices using a
NOTE The display module will revert back to the old settings once turned off, unless the
