200X With Pm 148 Do 4 Dc 24V/2A Power Module; Configuration Of Et 200X With Power Module (Example) - Siemens SIMATIC ET 200X Manual

Product Overview
1.5 ET 200X with PM 148 DO 4
Function
The power module is an expansion module for ET-voltage feed. You can use
power modules to loop through or feed load voltage separately from multiple
supply points to the digital-output modules of the ET 200X.
You can integrate a maximum of 7 power modules into an ET 200X.
Switching load voltage ON/Off selectively
A separate load-voltage supply means that you can switch load voltage on and off
selectively for individual modules. The "DC 24V" LED on the power module
indicates whether or not load voltage is applied.
