External Connections
E5AN-H/E5EN-H
• A voltage output (control output 1, 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.
The voltage output (control output 2, for driving SSR) has basic insulation provided for the internal circuit
