Power Modules
Note
The PM-E 24–48 VDC, 24–230 VAC power module (6ES7138-4CB10-0AB0) is not
a direct replacement for the device with the order number 6ES7138-4CB00-0AB0
for AC applications because you have to select either AC or DC supply voltage. In
the case of DC applications, the new module is a direct replacement because the
default setting of the new parameter is "DC". If you want to replace the device
6ES7138-4CB00-0AB0 in AC applications, you have to create a new hardware
configuration and set the value "AC" for the load voltage type parameter.
If the hardware configuration is not changed for AC applications, the SF status
LED remains on all the time. If the "No load voltage" diagnostic interrupt is
enabled, several interrupts are activated in each AC cycle. The electronic modules
that are connected to the potential group of this PM-E continue to function
normally, however.
