|16 CHANNEL RELAY OUTPUT BOARD
|The 16 Channel Relay Output board provides 16 Single
Pole Double Throw (SPDT) relays to drive 16 digital output lines.
Each of relay channels can be used to control ON/OFF of external
devices, to drive external high power relays, to activate
alarmsÂ¡Ketc. There are 16 LED indicators correspond to 16
relays, when relay is energized, the corresponding LED is light. The
+12V power source is user selectable from internal PC bus or external
The features of 16 Channel Relay Output Board is:
#Support 16 SPDT relay channels.
#LED indicates when relay is energized.
#Internal and external power selectable.
#Built in screw terminals for easy wiring.
#The Normal Open (NO), Normal Close (NC), and Common contacts (COM) of each relay are brought out to the screw connector.
#Max contract rating: 150V/DC 2amp, 125V/AC 2 amp.
#Breakdown voltage: AC/DC 500V minimum/
#Relay on time: 3 ms typical.
#Relay off time: 2 ms typical.
#Total switching time: 10 ms typical.
#Isolation resistance: 100 M OHM minimal.
#Life expectancy: 5 million operations at full load.
#Screw terminal: accept #22 to #12 awg wire.
Configuration For Jumper
Setting the threshold voltage of Photo Isolator, adjust VR, which is on the PCB to get the desired threshold voltage. The external input voltage, which is over the threshold voltage, will be recognized as HIGH (1) and the relative led will be light. Otherwise that will be LOW (0) and led be off.
