CHAPTER 1 OVERVIEW
This chapter describes the overview of the Q64TCN.
(1) The Q64TCTTN and Q64TCRTN
• The Q64TCTTN and Q64TCRTN perform PID operation to reach the target temperature based on input from
an external temperature sensor. The modules control temperature by transistor output.
• The Q64TCTTN and Q64TCRTN possess the auto tuning function by which proportional band (P), integral
time (I) and derivative time (D) for PID operation are automatically set.
• The Q64TCTTN accepts type K, J, T, B, S, E, R, N, U, L, PL II, and W5Re/W26Re thermocouples. The
Q64TCRTN accepts type Pt100 and JPt100 platinum resistance thermometers.
