Power supply units
For the supply of the modules, power supply units according to PELV specifcations must be used.
Electromagnetic Compatibility
Immunity
Against electrostatic discharge (ESD) According to EN 61000-4-2, zone B, criterion B
Electrostatic voltage in case of air discharge 8 kV
contact discharge 4 kV, in a closed switch-gear cabinet 6 kV (1)
ESD with communication connectors In order to prevent operating malfunctions, it is recommended, that the
operating personnel discharge themselves prior to touching communication
connectors or perform other suitable measures to reduce effects of
electrostatic discharges.
ESD with connectors of Terminal Bases The connectors between the terminal bases and CPUs or communication 4
modules must not be touched during operation. The same is valid for the
I/O-Bus with all modules involved.
Against the infuence of radiated (CW radiated) According to EN 61000-4-3, zone B, criterion A
Test field strength 10 V/m
Against transient interference voltages (burst) According to EN 61000-4-4, zone B, criterion B
Supply voltage units AC / DC 2 kV
Digital inputs/outputs 24 V DC 2 kV
120/230 V AC 2 kV
Analog inputs/outputs 1 kV
CS31 system bus 2 kV
Serial RS485 interfaces (COM) 2 kV
Serial RS232 interfaces (COM, not for PM55x and PM56x) 1 kV
ARCNET 1 kV
FBP 1 kV
Ethernet 1 kV
I/O supply, DC-out 1 kV
Against the infuence of line-conducted interferences (CW conducted) According to EN 61000-4-6, zone B, criterion A
Test voltage 3 V zone B, 10 V is also met
High energy surges According to EN 61000-4-5, zone B, criterion B
Power supply DC 1 kV CM (2) / 0.5 kV DM (2)
DC I/O supply 0.5 kV CM (2) / 0.5 kV DM (2)
Buses, shielded 1 kV CM (2)
AC-I/O unshielded 2 kV CM (2) / 1 kV DM (2)
I/O analog, I/O DC unshielded 1 kV CM (2) / 0.5 kV DM (2)
Radiation (radio disturbance) According to EN 55011, group 1, class A
(1) High requirement for shipping classes are achieved with additional specifc measures (see specifc documentation).
(2) CM = Common Mode - DM = Differential Mode.
