#06, M2T: Two High-Power Relays
Function: Two mechanical high-power relays with normally opened and normally closed terminals
Form factor: M2T
Category: Output module
Special needs: ---
Power requirements: 5V/140mA (with both relays activated)

Details
These relays have a contact capacity rated of 16A/48V (resistive load).
To activate a relay, set the corresponding control line LOW. When left unconnected, the control lines default to HIGH (and, hence, the relays are off).
Combine Tibbit #06 with #20 (nine terminal blocks).
LEDs
There are two red LEDs connected to the two relay control lines. The LEDs light up for the LOW state of the control lines (i.e., when the relays are activated).
