the ALARM output or by connecting an alarm output indicator. It’s not possible to connect both the Input Unit
and the indicator at the same time. Unless the external I/O power supply is connected and turned ON, the
indicator will not light even if the output contact turns ON.
Terminal Connections
+24 VDC
24 VDC
0 V
Note When the ALARM output turns ON, remove the cause of the high current and then shut off the external
power supply for approx. 1 second. After confirming that the cause has been removed, turn ON the power
supply again to reset the output. As shown in the diagram, it is recommended that a relay or switch that turns
ON or OFF only the external power supply be connected right before the B9 (+V). Check that this relay or
switch has a contact capacity higher than the external power supply current consumption (35 mA + load
current minimum).
