1-1-1 Introduction
The CJ1W-TC @@@ Temperature Control Units are Special I/O Units that
receive inputs directly from thermocouple or platinum resistance thermome-
ters, perform PID control with two degrees of freedom, and output results
through open collector outputs.
There are two main types of Unit: One provides four control loops and the
other provides two control loops with a heater burnout detection function.
Each of these has one model that is compatible with thermocouples (R, S, K,
J, T, B, or L) and another model that is compatible with platinum resistance
thermometers (JPt100 or Pt100). Both NPN outputs and PNP outputs are
available.
Autotuning of the PID control is also possible.
