External Connections - Omron E5CN Features

External Connections

• A voltage output (control output) 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.
• Standard insulation is applied between any of the following: power supply terminals, input terminals, output terminals, and communications
terminals (for models with communications). If reinforced insulation is required, provide additional insulation, such as spacial distance or
material insulation, as defined by IEC 60664 suitable for the maximum operating voltage.
• Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.

Terminals 11 to 15 do not exist on models without an Option Unit (heater burnout detection, control output 2, event inputs, or communications).
Terminal applications depend on the model of the Option Unit. Refer to page 3.

The input power supply depends on the power supply specification of the
Controller and is either 100 to 240 VAC or 24 VAC/DC (no polarity).
Order the P2CF-11 or P3GA-11 Socket separately. (See page 13.)
