E5CN/E5CN-U

External Connections

• 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.)

• Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.

The E5

@N-@@@T@ is set for a K-type

thermocouple (input type = 5) by default. An

input error (

s.err) will occur if the input type

setting does not agree with the temperature

sensor. Check the input type.
