Omron E5CN Features

10 Digital Temperature Controllers E5CN/E5CN-U
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.

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).
Note: Output when an input error output is enabled
in the Advance Function Setting Level. If an
input error output is enabled, the a1-1
operation indication on the front panel will
not light and s.err will be displayed on the
No. 1 display.

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.)
Note: Output when an input error output is
enabled in the Advance Function
Setting Level. If an input error
output is enabled, the al-1
operation indication on the front
panel will not light and s.err will be
displayed on the No. 1 display.
