7.1 Voltage supply

The Safety extension module IndraControl XFE01.1-SY-01 is supplied with 12 V
via a separate connection.
The input voltage of the Safety extension module is DC 24 V (as per the require-
ments acc. to DIN EN 61131-2). The voltage is supplied from PELV power supply
units with safe separation acc. to EN 50178 and EN 60950-1.
