■ Upgraded Functions
The functionality of the E5CN, E5CN-U, E5AN, and E5EN was improved starting from December 2007
production.
The functionality of the E5GN was improved starting from August 2009 production.
The design of the front panel can be used to differentiate between the previous and upgraded models.
● E5CN/CN-U
The upgraded Controllers are basically compatible with the previous Controllers. Terminal
arrangements, terminal sizes, and panel mounting depth have not been changed.
● E5AN/EN
Although the upgraded Controllers are compatible with the previous Controllers, terminal arrange-
ments have been changed. Terminal sizes and panel mounting depth have not been changed.
● E5GN
Model numbers have changed accompanying the introduction of universal input capability. The
default setting of the input type parameter of the E5GN-@@@P (models with resistance thermom-
eters) has been changed from a Pt100 resistance thermometer to a K thermocouple. Make sure
the setting of the input type parameter agrees with the temperature sensor that is being used.
The terminal block has also been changed, which means the wiring methods and terminal
arrangement are different.
Other changes outlined in the following tables. Refer to relevant pages in the manual for details.
