-20 to +40 °C / -50 to +400 °C

 

 

(2mA constant current method)

Number of channels

4 channels

Conversion time

About 1s / 4 channels

Insulation

Between channel and PC

Photocoupler insulation

 

Between channels

Non-insulation

External power supply

24V DC ±10% 100mA max.

Internal current consumption

200mA max.

(5 V DC)

 

 

External wiring resistance

400 ohm max. / channel

External wiring

Shielded wire

Additional function

Linearization

Error detection

 

-20 to +40 °C (Pt100)

H7FFF is outputted at –25 °C or less, or at +45 °C or higher

-50 to +400 °C (Pt100/ Pt1000)

H7FFF is outputted at –60 °C or less, or at +410 °C or higher

Processing for disconnection (Note 2)

H7FFF is outputted to channel.

 

 

 

Note 1: The accuracy is the value when 10 minutes pass after the start of power feeding. Just after power is fed, the value may increase slightly. Because a resistance temperature detective has an error, confirm it beforehand.

Note 2: This is the case when the current terminal wiring is broken. In case the voltage terminal wiring is broken, the data becomes unspecified. (“H” of “H7FFF” means the following data is hexadecimal.)
