Easy to use small size controller at reasonable price
CE RoHS compliance
LT 23A series is a 48x48mm digital indicating controller with
indicating accuracy of ±0.5% and the control cycle of approximately
0.5 seconds.
There are two type of mounting methods, terminal block type
and socket type.
3 types of auto tuning functions and overshoot suppression
functions are provided and highly safe control is achieved.
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.
