#03-2, M1S: Two Low-power Relays (Configuration 2)
Function: Two mechanical low-power relays with joined middle (common) terminals.
Relay 1 has normally closed and normally opened terminals. Relay 2 only has the
normally opened terminal exposed.
Form factor: M1S
Category: Output module
Special needs: ---
Power requirements: 5V/60mA (with both relays activated)
Mates with: #19, #20, #21
See also: #03-1, #06, #07, #15, #58, #59
Details
These relays are rated for 1A/30V.
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 terminal block devices -- #20 (nine terminal blocks) or #21
(four 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).
