(3) Connection of thermocouples compatible with JIS, IEC, NBS and
ASTM Standards
(a) The Q62HLC accepts the following thermocouples compatible with the JIS,
IEC, NBS and ASTM Standards. (Refer to Section 3.2.1)
• JIS Standards : R, K, J, S, B, E, T • IEC Standards: R, K, J, S, B, E, T, N
• NBS Standards : PL II
(4) Connection of sensors compatible with various input ranges of
micro voltage, voltage and current
With the input sensor for micro voltage, voltage and current, the measuring of the
analog input is available within the following ranges.
• Micro voltage : 0 to 10mV, 0 to 100 mV, -10 to 10 mV, -100 to 100 mV
• Voltage : 0 to 1V, 1 to 5V, 0 to 5V, 0 to 10V, -1 to 1V, -5 to 5 V, -10 to 10V
• Current : 4 to 20mA, 0 to 20mA
(5) RFB limiter function
The RFB (Reset Feed Back) limiter suppresses overshooting which is liable to
occur at a startup or when the set values (SV) is increased. (Refer to Section
3.2.4)
(6) Sensor compensation function
By setting a sensor compensation value, the sensor compensation function
eliminates a difference between measured values (PV) and actual temperature,
humidity, pressure, flow rate or others, if any. (Refer to Section 3.2.5)
(7) Program control function
By merely setting the program pattern, the function performs the control
automatically changing the set values (SV) or PID constants (proportional band
(P), integral time (I), derivative time (D)) by the hour. (Refer to Section 3.2.12)
(8) Cascade control function
The cascade control can perform the control using the channel 1 as master and
the channel 2 as slave. (Refer to Section 3.2.13)
(9) Scaling function
The result scaling the measured value (PV) can be automatically stored in the
buffer memory. (Refer to Section 3.2.14)
(10) Simplified analog I/O function
Monitoring the measured value and setting the manipulated value manually can
use the Q62HLC as simplified thermocouple/micro voltage input module, analog-
digital conversion module and digital-analog conversion. (Refer to 3.2.15)
(11) Auto tuning mode setting function
Setting AT (auto tuning) differential gap and AT additional lag can set the auto
tuning mode according to a control target to be used. (Refer to 3.2.2)
• ASTM Standards: W5Re, W26Re
