LT23A SERIES Digital Indicating Controller CE RoHS compliance

LT23A SERIES Digital Indicating Controller CE RoHS compliance
Digital Indicating Controller
LT23A SERIES
Easy to use small size controller at reasonable price
CE RoHS compliance
LT 23A series is a 48×48mm 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.
■FEATURES
■MODELS
●Compact design
Short depth of instrument (case 60mm) saves the space of instrument
and control board.
●Enriched input types
Thermocouple group, resistance thermometer group, DC voltage / DC
group can be selected. Input types can be changed within each group.
●Outstanding controllability
Control system can be selected from two-position control, PID control
and self-tuning.
It has overshoot suppression function and high functionality PID.
●3 type of auto tuning
Can be selected from normal, rapid-response, safe tuning on the control
target.
●Various input / output signal (optional) are available
Current transformer input 2 points, event output 3 points (Max), remote
signal input 2 points, communication interface (RS485).
●Terminal block type and socket type are available
●Conformance to international safety standards
Conformance to CE marking, RoHS
●Loader software is available
Various parameter settings and data acquisition can be done easily using
loader software (sold separately) .

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.
