min/s unit: −0.05% −1 s max. (rate for set value)

h/min unit: −0.05% −1 min max. (rate for set value)

Maximum counting speed

150 Hz: 8-Digit counter (F) set to high-speed operations (CPU Units with DC power supplies only)

(The counting speed may be less than 150 Hz depending on the cycle time of the program. See page 21.)

Insulation resistance

20 MΩ (at 500 VDC) min.:

Between power supply terminals and all output terminals.

Between terminals of different output circuits.

Between all terminals of CPU Unit and all terminals of Expansion I/O Unit.

Insulation

• Reinforced insulation

Between power supply or input terminals and output terminals.

Between terminals of different output circuits.

Between all terminals of CPU Unit and all terminals of Expansion I/O Unit.

• No separation

Between power supply and input terminals of the same unit.

Between power supply terminals of CPU Unit and computer connector,

Battery Unit connector, or all Expansion Unit connectors (all interfaces are live parts).

Dielectric strength

2,300 VAC, 50/60 Hz for 1 min (leakage current 1 mA max.):
