Digital Indicating Controller PERFORMANCE SPECIFICATION CHINO 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. ■ FEATURES •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) . ■ PARTS NAMES OF FUNCTIONS Displays PV values (preset temperature,etc) or settings items. Displays SP values (set temperature,etc) and other parameter values. RDY : Lights when READY (Control stop) MAN : Lights when MANUAL (manual mode) EV1 to EV3 : Lights when event outputs are ON. O1 to O2 : Lights when the control output is ON. The operations which has been set beforehand can be done by pushing the key for 1s or more. The function is disabled at factory default. Switches the display. Used for incrementing numeric values and performing arithmetic shift operation. Connects to a personal computer by using USB loader cable. *1: Cannot be selected for the socket type *2: Only 1a contact applicable for the socket type *3: Current transformer is sold separately *4: Socket is sold separately *5: Cannot be selected for 24V AC/DC power supply Note) For ON-OFF pulse 2 control outputs, even output (option) will be used as control outputs. There is 3 points (common) and 2 points (independent contact) so please select depending on the usage.

LT23A Series 48x48mm compact body IP66 protection structure of dust and water proof 60mm 48mm Compact body of 48x48mm and 60mm in depth. There is not only panel mounting type but also socket type, so it can correspond to multiple types of installations such as panel mounting type and DIN rail mounting type. Front of LT23A employs IP66 protection structure of dust-proof and water-proof.
