±(0.4% of F.S. +1°C 1.8°F) (at 0 to 55°C 32 to 131°F)

Platinum resistance thermometer

±0.2% of F.S. (at 25°C ±5°C 77°F ±9°F)
±0.4% of F.S. (at 0 to 55°C 32 to 131°F)

Allowable wiring resistance

100 Ω max./wire
(no variation allowed among three wires)

Conversion speed

125 ms/channel

Isolation method

Between input terminals and base unit:
Photocoupler/semiconductor relay/transformer isolation
Between channels: (When resistance thermometer is not used):
Semiconductor relay isolation;
(When resistance thermometer is used): No isolation

Special function

Channel skip, disconnection detection,
averaging (time average, count average, moving average),
special data offset, peak-/bottom-hold, alarm,
abnormal input setting

Internal current consumption

40 mA or less


Approx. 110 g

*1 Individual setting is possible for each channel.
