• The following table shows the specifications for each output type.
E5CN/CN-U
E5AN/EN
• Always connect an AC load to a long-life relay output. The output will not
turn OFF if a DC load is connected.
• The voltage output (for driving SSR) is not electrically isolated from the
internal circuits. When using a grounding thermocouple, do not connect
any of the control output terminals to the ground. If a control output termi-
nal is connected to the ground, errors will occur in the measured tempera-
ture as a result of leakage current.
