EMC
(See note.)
Note: EMC conforms to EN 61131-2 clause 8 except in the following cases.
• When Expansion I/O Units with DC inputs are connected to a CPU Unit with an AC power supply, the burst immunity between power
supplies will be 1 kv.
• When the signal wire for transistor outputs exceeds 10 m, the surge immunity of DC output signal lines will not conform.
