■ Approved Standards

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.

■ Input Specifications

CPU Units

AC Inputs (Not Isolated)

Note: Can be selected using the filter settings.

DC Inputs: I0 to I3 for Units with 10 I/O points, I0 to I9 for Units with 20 I/O Points (Not Isolated)

Note: Can be selected using the input filter settings, except when I0 is being used for an 8-digit counter with a high-speed input.
