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/ max. (100 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.
