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
Weight
Approx. 110 g
*1 Individual setting is possible for each channel.
