LT45A/47A SERIES Digital Indicating Controller
Digital Indicating Controller
LT45A/47A SERIES
LT45A/47A series is digital indicating controller with
indicating accuracy of ±0.1% and the control cycle of
approximately 0.1 second.
3 types of auto tuning functions and overshoot
suppression functions achieve superior control
stability.
Combination of internal computing function and
enriched input and output option support various
usage scenarios.
Special loader software provides ease of setting
operations and data acquisition.

Time
Time
In addition to the conventional PID, “High-performance
PID” is available which has unique algorithm aim to
converge hunting quickly to decrease settling time.
By “Overshoot suppression function” which controls overshoot at SP
changing and/or disturbance response, the control has been able to
develop stronger resistance for disturbance and superior stability.
Three types of Auto tuning
Step control
Along with the standard algorithm, auto tuning for a target which has
relatively good responsiveness and for a target which has good heatretention are provided to perform appropriate control easily.
Preset maximum 8
setting values and
each step can reserve hold time and
ramp setting. This
function
delivers
maximum 8 steps
program control
Zone PID control
STEP1 STEP2
STEP3
STEP4
When PID parameter change is necessary depending on the
temperature range such a case as furnace temperature control, preregistered 8 groups of PID parameters are assigned to every set
temperature ranges (max. 8 zones) and perform operation by
automatically changing the parameter depending on the measuring
value (or setting value).

Operation
3 points of event can be output
Result of the logical operation which performed on selected five points
of various internal events is able to be assigned to the three points of
external digital outputs. It can simplify process of event outputs which
logical operation was conventionally performed on receiver side.
Various parameter settings and data acquisition are available by connecting
this controller to the PC which the loader software is installed.
