Table 7.3: Performance specifications

Item Specifications

Conversion speed

• When only voltage input and current input are used

500 µs x Number of used channels

• When thermocouple input is used for 1 or more channels

Channel for voltage/current input: 1 ms x Number of used channels

Channel for thermocouple input: 40 ms x Number of used channels

(Number of used channels indicates number of all channels used for voltage

input, current input or thermocouple input.)

Insulation method Photocoupler insulates analog input area from PLC.

DC/DC converter insulates power supply from analog I/O.

Channels are not insulated each other.

Number of occupied

I/O points 8 points (including input points and output points)

Applicable PLC FX0N, FX1N, FX2N, FX2NC Series PLC

(For connection to FX2NC Series PLC, FX2NC-CNV-IF is required.)

Built-in memory EEPROM
