Preface
Conventions Used in This
Manual
Meanings of Abbreviations
The following abbreviations are used in parameter names, figures, and in text
explanations. These abbreviations mean the following:
➊A heater short indicates that the heater remains ON even when the control output from the Temperature
Controller is OFF because the SSR has failed or for any other reason.
➋“EU” stands for Engineering Unit. EU is used as the minimum unit for engineering units such as °C, m, and g.
The size of EU varies according to the Input Type.
For example, when the input temperature setting range is –200…+1300°C, 1 EU is 1°C, and when the input
temperature setting range is –20.0…+500.0°C, 1 EU is 0.1°C.
For analog inputs, the size of EU varies according to the decimal point position of the scaling setting, and 1 EU
becomes the minimum scaling unit.
Note: For additional definitions of terms used in this manual, refer to
Appendix D, Glossary.

Series B Controllers
Series B Upgrades
Series B controllers have the following upgrades.
900-TC8x
Although the upgraded controllers are compatible with the previous
controllers, terminal arrangements have been changed. Terminal sizes and
panel mounting depth have not been changed.
Other changes are outlined in the following tables. Refer to the relevant pages
in the manual for details.
900-TC16x
The upgraded controllers are basically compatible with the previous
controllers. Terminal arrangements, terminal sizes, and panel mounting depth
have not been changed.
900-TC32x
Model numbers have changed accompanying the introduction of universal
input capability. The default setting of the input type parameter of the
900-TC32x (models with resistance thermometers) 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.
