External Connections - Omron E5CN Datasheet

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.
