Status Output
There are two status outputs. They are driven by an optical coupler. These outputs work in any mode, and can be used as
status inputs for PLC or any status display/monitor purpose.
•
System Health -
Output low to indicate the unit is normally working.
•
LED State -
Output low to indicate the UV LEDs are ON.
The example application of these signals is shown below in Figure 20.

Status Outputs Connection Using On-Board 24V Source
PLC Power channel is a 24V source available for use to drive PLC logic but must be current limited using pull-down resistors
to protect the BlueWave AX-550 when directly attached to the I/O channels through the PLC connector.

PLC Status Outputs Using Customer-Supplied 24V Source
For sinking current below 7mA it is suggested when using solid state relays to use one of these devices:
