Details
This Tibbit is optimized for the nominal input voltage of 24V. If no external resistor is
added these inputs activate at about 13V. Forward current should not exceed
10mA, and this caps the maximum input voltage at around 30V. Add external
resistors if you need to apply higher input voltage.
Combine this Tibbit with terminal block devices --
(four terminal blocks).
LEDs
There are two green LEDs which are connected to two control lines. LEDs light up
for the LOW state of control lines (i.e. when current passes through the diodes of
the opto-couples).
