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.

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).

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

panel will not light and

s.err will be

displayed on the No. 1 display.
