Safety test for the -4UA13/-4UA14 modules
Immunity from conducted interference on signal
line 1 kV to IEC 801-4 (burst) for -4UA13 module
2 kV to IEC 801-4 (burst) for -4UA14 module
Immunity from discharge of static electricity 8 kV discharge in air to IEC 801-2, equivalent to 4 kV con-
tact discharge (see Chap. 3 and page 4-16)
6 kV contact discharge for -4UA14 module
1) Supply and signal voltages must be produced as functional voltage with safety separation.
2) The supply voltage range values are limit values. They include ripple.
3) If not otherwise specified
4) Must be bridged by the signal receiver
