Digital communications
MODBUS/ANSI protocol
The SA200 offers an optional RS-485 communications
interface for networking to computers, PLCs and SCADA
software. MODBUS or ANSI protocol can be selected. Up to
32 units, including host computer, can be multi-dropped on one
RS-485 communication line. When the communication feature
is selected, the external contact input is not available.

Digital Temperature
Controller
RKC self-tuning
Advanced algorithm for optimum control
RKC self-tuning offers the most advanced algorithm for precise
temperature control. Self-tuning is initiated at start-up and
when process parameters or conditions change.
times, new PID parameters are calculated for the best control
performance. With the unique RKC self-tuning, the controller
evaluates whether PID parameters should be maintained or
replaced, selecting the best setting for the controlled process. If
it is determined that the existing PID parameters can achieve
the best control for the process, the present PID parameters will
be retained and the new PID parameters will be canceled. Self-
tuning can be turned on/off in parameter setting mode. Self-
tuning is not available with heat/cool control.
In addition to self-tuning, the controller also has autotuning
(AT) so that either function can be selected for optimum process
control.
