302Tibbo Project System (TPS)

Details
These relays have the contact capacity rated at 16A/48V (resistive load).
To activate a relay, set the corresponding control line LOW. When left
unconnected, control lines default to HIGH (and, hence, relays are off).
Combine this Tibbit with Tibbit #20 (nine terminal blocks).
LEDs
There are two red LEDs which are connected to two relay control lines. LEDs light
up for the LOW state of control lines (i.e. when relays are activated).
