Electromagnetic Compatibility¶
| Immunity | ||
|---|---|---|
| Immunity against electrostatic discharge (ESD): | According to EN 61000-4-2, zone B, criterion B | |
| Electrostatic voltage in case of air discharge | 8 kV | |
| Electrostatic voltage in case of 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 Processor Modules or Communication Modules must not be touched during operation. The same is valid for the I/O-Bus with all modules involved. | |
| Immunity against the influence of radiated (CW radiated): | According to EN 61000-4-3, zone B, criterion A | |
| Test field strength | 10 V/m | |
| Immunity against transient interference voltages (burst): | According to EN 61000-4-4, zone B, criterion B | |
| Supply voltage units (AC, DC) | 4 kV | |
| Digital inputs/outputs (24 V DC) | 2 kV | |
| Digital inputs/outputs (120/230 V AC) | 2 kV | |
| Analog inputs/outputs | 1 kV | |
| CS31 system bus | 2 kV | |
| Serial RS-485 interfaces (COM) | 2 kV | |
| Serial RS-232 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 | |
| Immunity against the influence of line-conducted interferences (CW conducted): | According to EN 61000-4-6, zone B, criterion A | |
| Test voltage | 3V 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 / 0.5 kV DM ²) | |
| DC I/O supply | 0.5 kV CM / 0.5 kV DM ²) | |
| Communication Lines, shielded | 1 kV CM ²) | |
| AC-I/O unshielded | 2 kV CM / 1 kV DM ²) | |
| I/O analog, I/O DC unshielded | 1 kV CM / 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 specific measures (see specific documentation).
