Details
Output transistors are rated for 24V/0.5A.
To activate a transistor, set the corresponding control line LOW. When left
unconnected, control lines default to HIGH (and, hence, transistors will be closed).
Combine this Tibbit with terminal block devices --
(four terminal blocks).
LEDs
There are two red LEDs, which are connected to two transistor control lines. LEDs
light up for the LOW state of control lines (i.e. when transistors are opened).
Typical connection diagram
The diagram below shows an external 24V power supply and two loads connected to
the outputs of Tibbit #58.
