(3) Connection of thermocouples compatible with JIS, IEC, NBS and
ASTM Standards
(a) Thermocouples compatible with the JIS, IEC, NBS, and ASTM Standards can
be connected to the Q62HLC.
• 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 the input ranges of micro
voltage, voltage and current
Analog input of the following ranges can be measured using the micro voltage,
voltage, and current input sensors.
• Micro voltage : 0 to 10mV, 0 to 100mV, -10 to 10mV, -100 to 100mV
• 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 that may occur at a
start-up or when the set value (SV) is increased (refer to Section 3.2.4).
(6) Sensor compensation function
By setting a sensor compensation value, a difference, if any, between the
measured value (PV) and actual temperature, humidity, pressure, flow rate, or
others can be eliminated (refer to Section 3.2.5).
(7) Program control function
The control can be performed automatically, changing the set value (SV) and PID
constants (proportional band (P), integral time (I), derivative time (D)) by setting a
program pattern (refer to Section 3.2.12).
(8) Cascade control function
The cascade control can be performed using the channel 1 as master and the
channel 2 as slave (refer to Section 3.2.13).
(9) Scaling function
The scaled measured value (PV) can be automatically stored in the buffer
memory (refer to Section 3.2.14).
(10) Simplified analog I/O function
The Q62HLC can be used as a simplified thermocouple/micro voltage input
module, analog-digital conversion module, or digital-analog conversion module
by monitoring the measured value and setting the manipulated value manually
(refer to Section 3.2.17).
(11) Auto tuning mode setting function
The auto tuning mode according to a control target can be specified by setting
AT differential gap and AT additional lag (refer to Section 3.2.2).
• ASTM Standards: W5Re, W26Re
