Digital Temperature Controllers

E5CN/E5CN-U

■ Characteristics

Note: 1. The indication of K thermocouples in the

-200 to 1300°C

range, T and N thermocouples at a temperature of

-100°C

max., and U and L thermocouples at any temperature is

±2°C ±1 digit maximum. The indication accuracy of the B

thermocouple at a temperature of 400

°C max. is not

specified. The indication accuracy of the R and S

thermocouples at a temperature of 200

°C max. is ±3°C ±1

digit max.

2. “EU” stands for Engineering Unit and is used as the unit

after scaling. For a temperature sensor, the EU is

°C or °F.

3. When robust tuning (RT) is ON, the differential time is 0.0 to

999.9 (in units of 0.1 s).

4. B, R, and S sensors: 0.2

°C/W max. (100 W max.)

■ Communications Specifications

Note: The baud rate, data bit length, stop bit length, and vertical

parity can be individually set using the Communications Setting

Level.
