Modular Temperature Controller EJ1 3
■ Characteristics
Note: 1. The indication of K thermocouples in the −200 to 1,300°C range, T and N thermocouples at a temperature of −100°C or less, and U and
L thermocouples at any temperature is ±2°C ±1 digit maximum. The indication of B thermocouples at a temperature of 400°C or less is
unrestricted. The indication of R and S thermocouples at a temperature of 200°C or less is ±3°C ±1 digit max.
W = (±0.5% of indication value (PV) or ±3°C, whichever is greater) ±1 digit max. PLII = (±0.5% of indication value (PV) or ±2°C, whichever
is greater) ±1 digit max.
2. “EU” stands for Engineering Unit. The location of the decimal point depends on the type of sensor that is selected.
If the decimal point locations is set to 0 (****), however, it will be treated as if it were set to 1 (***.*).
3. B, R, S, and W sensors: 0.2°C/
Ω max. (100 Ω max.)
Indication accuracy Thermocouple input/platinum resistance thermometer input:
(±0.5% of indication value (PV) or ±1°C, whichever is greater) ±1 digit max. (See note 1.)
