Basic-type Digital Temperature Controller
New 48 x 48-mm Basic Temperature
Controller with Enhanced Functions and
Performance. Improved Indication
Accuracy and Preventive Maintenance
Indication Accuracy
Thermocouple input: ±0.3% of PV (previous models: ±0.5%)
Pt input: ±0.2% of PV (previous models: ±0.5%)

    A voltage output (control output, for driving SSR) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect any of the control output terminals to ground. (If the control output terminals are connected to ground, errors will occur in the measured temperature values as a result of leakage current.)
