• The PID with advanced feed-forward circuitry (2 degrees of freedom) of the
CQM1-TC00j/TC10j assures stable temperature control. The Units can be
set to ON/OFF control.
• CQM1-TC00j
Temperature
CQM1-TC10j Temperature Control Units for platinum resistance thermome-
ters are available. Each Temperature Control Unit can be used for two-loop
temperature control.

• One word each can be allocated for inputs and outputs if only one control loop
is used (when DIP switch pin 5 is ON).
• Two words each will be allocated for inputs and outputs if two control loops are
used (when DIP switch pin 5 is OFF),
• Data is handled as four digits of BCD, except that an F in the leftmost digit is
used to indicate negative values. The meaning of each digit is shown below.

• The set point setting range is as follows:
F999 to 9999, or CCCC
• The contents of the process value is as follows:
F999 to 9999: Process value
