Accuracy (Setting, indication)
Thermocouple : Within ±0.2 % of input range full scale ±1 digit or
within ±2 °C (4 °F), whichever is greater
However, R, S inputs, 0 … 200 °C (0 … 400 °F): Within ±6 °C (12 °F)
B input, 0 … 300 °C (0 … 600 °F): Accuracy is not guaranteed.
K, J, E, T, N inputs, less than 0 °C (32 °F): Within ±0.4 % of input
range full scale ±1 digit
RTD : Within ±0.1 % of input range full scale ±1 digit or
within ±1 °C (2 °F), whichever is greater
DC Voltage and Current:
Within ±0.2 % of input range full scale ±1digit
Input sampling period : 0.25 seconds
Control output (OUT1)
Relay contact : Control capacity, 3 A, 250 V AC (resistive load)
1 A, 250 V AC (inductive load cos ø = 0.4)
Electrical life 100,000 times
Logic level DC 0/12 V for solid state relay:
12 + 2
- 0
V DC maximum 40 mA (short circuit protected)
Analogue current signal : 4 … 20 mA DC
Load resistance, maximum 550 Ω
A1 output
When A1 action is set as energized, the alarm action point is set by ±deviation to the main setting
(except Process alarm).
When the input exceeds the range, the output turns ON or OFF (in the case of High/Low limit
range alarm).
When the alarm action is set as deenergized, the output acts conversely.
Setting accuracy : The same as the Indicating accuracy
Action : ON/OFF action
Hysteresis : Thermocouple and RTD inputs, 0.1 … 100.0 °C (°F)
DC current and DC voltage inputs, 1 … 1000
(The placement of the decimal point follows the selection)
Output : Relay contact 1a
Control capacity 3 A, 250 V AC (resistive load)
Electrical life 100,000 times
Control action
• PID action (with auto-tuning function)
• PI action: When derivative time is set to 0
• PD action (with auto-reset function): When integral time is set to 0
• P action (with auto-reset function): When integral and derivative times are set to 0
• ON/OFF action
OUT1 proportional band (P):
Thermocouple, 0 ... 1000°C (0 ... 2000°F)
RTD, 0.0 ... 999.9°C (0.0 ... 999.9°F)
DC current and voltage, 0.0 ... 100.0%
(ON/OFF action when set to 0°C (°F), 0.0°C (°F) or 0.0%)
Integral time (I) : 0 ... 1000 s (off when set to 0)
Derivative time (D) : 0 ... 300 s (off when set to 0)
OUT1 proportional cycle : 1 ... 120 s (Not available for control output analogue current signal)
ARW : 0 ... 100 %
OUT1 hysteresis : Thermocouple and RTD inputs, 0.1 ... 100.0 °C (°F)

SV1/SV2 external selection : SV1 and SV2 can be selected by external contact.
Contact open between terminals 14 and 17 : SV1
Contact closed between terminals 14 and 17 : SV2
Contact current: 6mA
