Features
The basic features of the Thermac E5
J Temperature Controller are outlined
below.
Fuzzy Self-tuning
When using a conventional temperature controller for ideal temperature control,
it is necessary to adjust the PID constants of the temperature controller accord-
ing to the controlled device. The Thermac E5
J Temperature Controller incor-
porates a fuzzy self-tuning function, thus allowing ideal temperature control
without any adjustment of the PID constants. The user needs only to set the
E5
J to the desired temperature for ideal temperature control.
Auto-tuning
Auto-tuning is also available. It is useful when appropriate results are not
obtained through fuzzy self-tuning. (Refer to
Section 10 Auto-tuning.)
Event Input Function
It is possible to select a set point out of a maximum of two set values on the
E5CJ-
B and four set values on the E5AJ-
B via their event input terminals
from the PCs connected to these Temperature Controllers. The control opera-
tion of the E5AJ-
B via can be stopped with an event input signal.
Watertight Construction
The E5
J can be used in places where water is sprayed onto the E5
J, be-
cause the front panel of the E5
J assures IP54 when the E5
J is panel-
mounted (except for front panel of the E5CJ, which assures IP50). If greater wa-
tertightness is required, use the Y92A-
N, a dedicated watertight cover (sold
separately).
The E5
J incorporates an advanced PID function, which is also incorporated by
the Thermac X Temperature Controller. The advanced PID function prevents
temperature overshooting the moment the Temperature Controller starts oper-
ating, assures a short startup time, and performs ideal temperature control by
quickly responding to external disturbances.
Output Units
The E53-R Relay Unit, E53-Q, E53-Q3, and E53-Q4 Voltage Output Units for
driving SSRs, and E53-C3, E53-C3D, E53-V34, and E53-V35 Linear Output
Unit can be connected to any E5
J Temperature Controller (except the E5CJ)
with ease according to the desired output configuration and application.
