#07, M1S: Two Solid State Relays
Function: Two solid state normally opened relays
Form factor: M1S
Category: Output module
Special needs: ---
Power requirements: 5V/25mA (with both relays activated)

Details
These relays are rated for a maximum load of 1A per relay.
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 #07 with terminal block devices — #20 (nine terminal blocks) or #21 (four 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).
