Basic-type Digital Temperature Controller

E5CN/E5CN-U

New 48 x 48-mm Basic Temperature
Controller with Enhanced Functions and
Performance. Improved Indication
Accuracy and Preventive Maintenance
Function.
• Indication Accuracy
Thermocouple input: ±0.3% of PV (previous models: ±0.5%)
Pt input: ±0.2% of PV (previous models: ±0.5%)
Analog input: ±0.2% FS (previous models: ±0.5%)
• New E5CN-U Models (Plug-in Models) with analog inputs and
current outputs.
• A PV/SV-status display function can be set to automatically
alternate between displaying the status of the Temperature
Controller (auto/manual, RUN/STOP, and alarms) and the PV or SV.
• Preventive maintenance for relays in the Temperature Controller
using a Control Output ON/OFF Counter.
