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) .

PSE-809 LT23A Series 48x48mm compact body IP66 protection structure of dust and water proof 48mm 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. Advanced controllability Overshoot suppression factor Small (SP) (SP) PV PV Overshoot suppression factor Large High-performance PID PID Time Time 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 RUN/READY to the FUNC key, only one press of a button enables switching the functions.

However, it requires exclusive loader cable (sold separately). Internal event can be output as external contact output by logical operation Loader software (sold separately) On LT23A… Event 1 Event 2 Event 3 Program 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. 2 ■ SPECIFICATIONS ●Input specifications ●General specifications Input signal: Operation temperature: 0 to 50℃ Power supply voltage range: AC power supply model 100 to 240 V AC, 50/60Hz DC power supply model 24 V AC, 50/60Hz/24V to 48V DC Power consumption: AC power supply model 12 VA or/and lower DC power supply model 7 VA or/and lower (24V AC) 5W or/and lower (24V DC) Safety standards: CE marking compliant product Structure: IP66 (front part) Weight: Terminal block type: 150g Socket type: 200g (including socket) Group selection by the models (Thermocouple, Resistance Thermometer, DC voltage/current) Range type: Refer to a measuring range table Input sampling cycle: 500ms Accuracy rating: ±0.5%FS±1digit ●Control specifications Output type: ON-OFF pulse output type:1c 250V AC, 30V DC 3A (resistance load) Current output type: 0 to 20 A DC, 4 to 20 mA DC (It can be changed by the setting) SSR drive pulse output type: 19V DC±15%, Internal resistance 82Ω, Allowable current Max. 24mA DC ■ ACCESSORY (Sold separetely) ■ ACCESSORY Item Model Item Model Attachment (for terminal block type) LTA-P205 Hard cover LTA-P202 Manual L2A-11-□ Soft cover LTA-P203 Gasket (for terminal block type) LTA-P206 Terminal cover LTA-P204 Current transformer LTA-P207 (5.8mm hole dia.), LTA-P208 (12mm hole dia.) ■ OPTIONAL SOFTWARE Attachment (for terminal block type) LTA-P205 LTA-P206 Item Model Gasket (for terminal block type) 20 pieces Loader software (cable included) LTA-S001 Socket LTA-P201 Loader software LTA-S002 Plug coversion cable for LT23A LTA-P209 Loader cable LTA-S003 Shunt resister 250Ω RZ-EX250 ■ MEASURING RANGE C01 Set value Input type K J Thermocouple E T R S B N Platinel WRe5-26 RTD DC voltage/current DIN U DIN L Pt100 JPt100 Pt100 JPt100 Pt100 JPt100 Pt100 JPt100 Pt100 JPt100 Pt100 JPt100 Pt100 JPt100 0 to 1V 1 to 5V 0 to 5V 0 to 10V 0 to 20mA 4 to 20mA 1 2 3 4 5 6 9 10 11 13 14 15 16 17 18 19 20 21 24 25 41 42 43 44 45 46 51 52 53 54 63 64 67 68 84 86 87 88 89 90 Measuring range -200 to 1200℃ 0 to 1200℃ 0.0 to 800.0℃ 0.0 to 600.0℃ 0.0 to 400.0℃ -200.0 to 400.0℃ 0.0 to 800.0℃ 0.0 to 600.0℃ -200.0 to 400.0℃ 0.0 to 600.0℃ -200.0 to 400.0℃ 0 to 1600℃ 0 to 1600℃ 0 to 1800℃ 0 to 1300℃ 0 to 1300℃ 0 to 1400℃ 0 to 2300℃ -200.0 to 400.0℃ -100.0 to 800.0℃ -200 to 500℃ -200 to 500℃ -200 to 200℃ -200 to 200℃ -100 to 300℃ -100 to 300℃ -50.0 to 200.0℃ -50.0 to 200.0℃ -50.0 to 100.0℃ -50.0 to 100.0℃ 0.0 to 200.0℃ 0.0 to 200.0℃ 0 to 500℃ 0 to 500℃ Measuring accuracy ±0.5%FS±1digit Minus area is ±1.0%FS±1digit Range with decimal point is ±0.5%FS±2digit Under 260℃：±5%FS,260-800℃：±1%FS Minus area is ±1.0%FS±2digit ±0.5%FS±1digit The scaling and decimal point position can be changed variably in a range of -1999 to +9999 ±0.5%FS±1digit Lower limit of indication value of B thermocouple is 20℃ *●Applicable standards ・Thermocouple K,J,E,T,R,S,B,N : Platinel : WRe5-26 : DIN U,DIN L : JIS C 1602-1995 Engelhard Industries(ITS90) ASTEM E988-96(Reapproved 2002) DIN43710-1985 ・Resistance thermometer Pt100 : JIS C 1604-1997 JPt100 : JIS C 1604-1989 3 ■TERMINAL BOARD ●Terminal block type ●Socket type CT input Control output Control output Event output NO NO COM ON-OFF pulse ON-OFF pulse Relay NC NC Event output SSR driver pulse SSR driver pulse Relay Individual contact COM Relay SSR driver pulse Current Current Measurement input Relay Individual contact SSR driver pulse SSR driver pulse Power supply 100-240V AC Thermocouple Power supply Current Current Current Current 24V AC 24-48V DC (Non polar) Measurement input 24V AC 24-48V DC (Non polar) RTD 100-240V AC − Voltage Socket terminal number Thermocouple ●RS485 communication connection DI/communication 16 RTD 17 18 RS-485 Remote signal input Cautions for handling Current Do not connect the external resistor because this unit has a built in termination resistor.
