10 Digital Temperature Controllers E5CN/E5CN-U
External Connections
• Voltage outputs (control outputs) are 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 temper-
ature 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 ter-
minals (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 options (heater burnout detection, control output 2, event inputs, or communications).
Terminal applications depend on the model of the Controller.

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 14.)
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.
