Digital Indicating Controller LT45A/47A SERIES - 1

Digital Indicating Controller PERFORMANCE SPECIFICATION © [FUNC] key: © [DISPLAY]/[DSP] key: © [MODE] key: ®<,V,A Key : ® [ENT] key: ® Loader connector: *1 : Current transformer is sold separately. *2 : Current transformer input not available when ON-OFF servo output is selected as control output. Then it becomes motorized feedback input. 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. ■ FEATURES •Compact design Short depth of instrument (case 65mm) saves the space of instrument and control board. •Universal input Input type is user-changeable from among thermocouple, resistance thermometer, DC voltage and DC current. •Outstanding controllability Control system can be selected from two-position control and PID control. It has overshoot suppression function and high-functional PID. •3 types of auto tuning Can be selected from normal, rapid-response, stable 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 4 points and communication interface (RS485). •Conformance to international safety standards 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 (temperature, etc.). Displays SP values (preset temperature, etc.) or setting items. MAN: Lights when MANUAL (manual mode). RSP: Lights when remote SP input. (Local SP input when light OFF) EV1 to EV3: Lights when event outputs are ON 01 to 02: Lights when the control output is ON @ Multiple functions indicating lamp: User-settable max. 3 sets combination of condition and status as preferred functions (alarm, READY, etc.). Press 1 second or longer, then enters frequently used functions and operations set in advance. The function is disabled at factory default. Switch display in operation mode. Or back to operation mode from parameter setting mode. Switches the display Used for incrementing numeric values and performing arithmetic shift operation. Start to change setting and set value. Connects to a personal computer by using USB loader cable. 24V AC/DC power supply can not be selected. Non-conforming to CE, UL/cUL. Event output are 2 types, specify models of 3 point (common) or 2 points (independent).

LT45A/47A Series Compact Bodies Easy-to-read display On the display, measuring value (PV) is indicated in green and setting value (SP) is indicated in orange LEDs. Frequently used operation can be assigned to the FUNC key By assigning frequently used operation such as Auto/Manual and RUN/READY to the FUNC key, only one press of a button enables switching the functions. 65mm 48mm 96mm There are size 48x96mm and 96x96mm available. Depth is only 65mm, so it is space saving for any installation Advanced controllability Overshoot suppression factor Small Overshoot suppression factor Large In...
