Power modules
Note
The PM-E 24--48 VDC/24--230 VAC power module (6ES7 138-4CB10-0AB0) is not
a direct replacement for the device with the order number 6ES7 138-4CB00-0AB0
for AC applications, because either AC or DC power supply must be specified. The
new module is a direct replacement with DC applications, because the default for
the new parameter is "DC". If you wish to use the 6ES7 138-4CB00-0AB0 device
for AC applications, a new hardware configuration must be set up and the value
"AC" must be specified for the "Load voltage type" parameter.
If the hardware configuration is not changed for AC applications, the SF status
LED remains on continuously. If the "Lo load voltage" diagnostic alarm is activated,
multiple interrupts are activated in every AC cycle. However, the electronic
modules connected to the potential group of this PM-E operate normally.
Terminal assignment
