A logic “1” switches the appropriate relay driver on. A logic “0”
switches the appropriate relay driver off.
If you wish to install a relay driver, perform the following steps:
1.
Remove resistors from locations R22 to R29.
2.
Solder the relay driver in location U1 on the STP9820 while
observing the correct polarity.
Continue with the next section to attach the STP9820 screw terminal
panel to a DT9820 Series module.
Note:
Refer to
for information on how to connect relays to
the STP9820 once the relay driver is installed.
