• Manufacturer Part Number: E5CN
• Description: Digital Temperature Controllers
• Manufacturer: OMRON [Omron Electronics LLC]

External Connections
• A voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect
• Standard insulation is applied between any of the following: power supply terminals, input terminals, output terminals, and communications

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.
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.
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.
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).
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 14.)
