Single relay board for IR motion
detectors, proximity switches,... etc.,,
(#80321)
( positive input activates
relay)
This general purpose relay board can be
used with IR motion sensors, proximity switches (with active high output) to switch high current loads
The relay used is a SPDT (single pole double throw) type which can
handle current up to 10A.
OPERATION :
The relay is normally inactive & LED is off.
When a DC voltage is applied to the input (terminal S & GND), the relay
actuates & LED glows.
TESTING :
Power up the board by
connecting the Vdd & GND terminals to a suitable DC
power supply.
Initially the relay should be in the non-active state (
LED is off ).
Now apply a
positive voltage to the input by shorting the terminals
Vdd & input (S) with a test pen.
This will turn ON the relay & LED
NOTE :
The component
values printed on the PCB are meant for DC12V operation.
But it can be modified to work at other voltages by
changing the relay to a model with matching
voltage
(please see description &
application example below)
