Ordering Information
Special I/O Units
Isolated-type Thermocouple Input Units
Note: 1. The accuracy depends on the sensors used and the measurement temperatures. For details, refer to the user’s manual.
2. This is for an external power supply, and not for internal current consumption.
3. L and
−100°C or less for K and T are ±2°C±1 digit max., and 200°C or less for R and S is ±3°C±1 digit max. No accuracy is specified for
400
°C or less for B.
Isolated-type Resistance Thermometer Input Units
Note: This is for an external power supply, and not for internal current consumption.
Isolated-type DC Input Unit
Note: This is for an external power supply, and not for internal current consumption.
