General Accuracy

Thermocouples

±(0.2% of F.E. + 1°C (1.8°F)) (at 25°C ±5°C (77°F ±9°F))

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

Platinum Resistance Thermometers

±0.2% of F.E. (at 25°C ±5°C (77°F ±9°F))

±0.4% of F.E. (from 0 to 55°C (32 to 131°F))

Maximum Wiring Resistance

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

Conversion Speed

125 ms/channel

Isolation Method

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

Special Functions

• Channel omission, disconnection detection,
• Averaging (time average, count average, moving average),
• Special data compensation,
• Retention of peak/minimum value, alarm,
• Abnormal input configuration

Internal Current Consumption

40 mA or less

Weight

Approx. 110 g
