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:
Table P.A
Symbol Term
PV Process value
SP Set point
SV Set value
AT Auto-tuning
ST Self-tuning
HB Heater Burnout
HS Heater Short ➊
EU Engineering unit ➋
OC Overcurrent
LBA Loop Burnout Alarm
➊ A 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

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.

Bulletin 900-TC8, 900-TC16, and 900-TC32 temperature controllers allow the
user to:
• Select from thermocouple and platinum RTD temperature sensors, plus
non-contact temperature sensor and analog voltage or current inputs.
➊
• Individually assign the function for each output by changing the
configured values of the following parameters: Control Output 1,
Assignment, Control Output 2 Assignment
Assignment
➊, and Aux 3 Assignment (900-TC8).
➊, Aux 1 Assignment, Aux 2
• Select heating and cooling control in addition to standard control
• Select AT (Auto-Tuning) and ST (Self-Tuning) as tuning functions
• Use multi-SP, switch between automatic and manual operation,
start/reset the simple program function, and initiate the RUN/STOP
function according to event input.
➊
• Use the Heater Burnout Alarm (HBA) and Heater Short Alarm (HSA)
function.
➊
• Use the communications function (for units equipped with the optional
communications function modules)
• Calibrate sensor input
• Configure the color of the PV display to switch between amber, red, and
green, making the process status easy to understand at a glance.

Publication 900-UM007D-EN-E - January 2011

Features
• Watertight construction (equivalent to IP66 indoor use).
• Conform to cULus/IEC safety standards and EMC standards.
Main Functions
The following introduces the main functions of the Bulletin 900-TC8,
900-TC16, and 900-TC32 temperature controllers. For details on each
function and how to use them, refer to Chapter 3 and onward.
• Input Sensor Types — The following input sensors can be connected
for temperature input:
– Thermocouple: K, J, T, E, L, U, N, R, S, B, W, PL11
– Infrared non-contact temperature sensor type: Type K thermocouple
(10…70XC), K (60…120XC), K (115…165XC), K (160…260XC)
– Platinum resistance thermometer: Pt100, JPt100
– Analog millivolt input: 0…50 mV
• High level analog inputs:
– Current input:4…20 mA DC, 0 to 20 mA DC
– Voltage input:1…5V DC, 0…5V DC, 0…10V DC
• Control Output — Control output is either an On/Off
electro-mechanical relay (EMR) ON/OFF triac output (AC only)
On/Off voltage (input to solid-state relay) output, or analog current
(DC: 4...20 mA or 0…20 mA) output
• Triac Relay Outputs
closing andopening the AC voltage circuit, thereby eliminating relay
chatter and arcing and improving durability versus an EMR. However, if
high levels of noise or surge are imposed between the output terminals,
short-circuit faults may occasionally occur. If the triac output becomes
permanently shorted, there is the danger of fire due to overheating of
the heater element. To avoid this danger, design safety into the system,
including measures to prevent excessive temperature rise and fire. Take
countermeasures such as installing a surge absorber. As an additional
safety measure, provide error detection in the control loop. Use the
Loop Break Alarm (LBA) and Heater Short Alarm (HSA) that are
provided for Bulletin 900 temperature controllers.

• Always connect an AC load to the triac relay output. The output will not
turn OFF if a DC load is connected.
• Alarms — Alarms are supported on the Bulletin 900 temperature
controllers. You can configure the alarm type and alarm value, or Upper
and Lower-Limit alarms.
If necessary, a more comprehensive alarm function can be achieved by
configuring the Standby Sequence, Alarm Hysteresis, Close in
Alarm/Open in Alarm and Alarm Latch ON/OFF parameters.
When the input error output is configured to ON, Alarm Output 1
turns ON when an input error occurs.
• Control Adjustment — Optimum PID constants can be configured
easily by using the AT (Auto-Tuning) and ST (Self-Tuning) parameters.
• Event Input — When the optional event input unit is mounted, the
following functions can be achieved by event input:
Multiple set point selection (multi-SP max. 4 points), RUN/STOP
mode change switching between automatic and manual operation, and
starting/stopping the simple program. Refer to Table 1.C and 1.E.
• HBA and HS Alarms — The Heater Burnout Alarm (HBA) and
Heater Short Alarm (HSA) and heater overcurrent function is
supported by selecting the appropriate controller (900-TC8) or option
module (900-TC16). Refer to Table 1.B for the TC8 and Table 1.E for
the TC16.
• Communications Function — Personal computer (PC)
communicationsare supported when the option communications unit is
mounted on the temperature controller. Refer to Table 1.C and 1.E.
Note: The PC must have 900BuilderLite software installed.
Note: 900-TC protocol is an integrated general-purpose serial
communications protocol.

Note: Modbus is a communications control method conforming to the RTU.

Note: The 900-TC16 and 900-TC32 do not support the RS-232C interface.
