CX9020-0111 | BASIC CPU MODULE

THE CX9020-0111 IS A COMPACT, DIN RAIL-MOUNTABLE ETHERNET CONTROL SYSTEM WITH 1 GHZ ARM CORTEX™-A8 CPU. THE CONNECTION FOR 

THE BECKHOFF I/O SYSTEMS IS DIRECTLY INTEGRATED INTO THE CPU MODULE.

3x KL3448 | BUS TERMINAL, 8-CHANNEL ANALOG INPUT, VOLTAGE, 0…20 MA, 12 BIT, SINGLE-ENDED

THE KL3444 ANALOG INPUT TERMINAL PROCESSES SIGNALS IN THE RANGE BETWEEN 0 AND 20 MA. THE CURRENT IS DIGITISED TO A RESOLUTION OF 12 BITS AND IS TRANSMITTED, IN AN ELECTRICALLY ISOLATED FORM, TO THE HIGHER-LEVEL AUTOMATION DEVICE. THE KL3448 COMBINES EIGHT CHANNELS IN ONE HOUSING AND IS PARTICULARLY SUITABLE FOR SPACE-SAVING INSTALLATION IN CONTROL CABINETS. THE USE OF SINGLE CONDUCTOR CONNECTION TECHNOLOGY ENABLES THE CONNECTION OF MULTI-CHANNEL SENSOR TECHNOLOGY WITH MINIMUM SPACE REQUIREMENTS. THE REFERENCE GROUND FOR ALL INPUTS IS THE 0 V POWER CONTACT. THE POWER CONTACTS ARE CONNECTED THROUGH. OVERLOAD IS DETECTED. THE TERMINAL STATUS IS RELAYED TO THE CONTROLLER VIA THE K-BUS. THE LEDS

INDICATE THE DATA EXCHANGE WITH THE BUS COUPLER AS WELL AS OVERLOAD OR WIRE BREAKAGE.

17x KL3204 | BUS TERMINAL, 4-CHANNEL ANALOG INPUT, TEMPERATURE, RTD (PT100), 16 BIT

THE KL3204 ANALOG INPUT TERMINAL ALLOWS RESISTANCE SENSORS TO BE CONNECTED DIRECTLY. THE BUS TERMINAL’S CIRCUITRY CAN OPERATE THE SENSORS USING 2-WIRE CONNECTION TECHNIQUES. LINEARISATION OVER THE FULL TEMPERATURE RANGE IS REALISED WITH THE AID OF A MICROPROCESSOR. THE TEMPERATURE RANGE CAN BE SELECTED FREELY. THE BUS TERMINALS STANDARD SETTINGS ARE: RESOLUTION 0.1 °C IN THE TEMPERATURE RANGE OF PT100 SENSORS. THE ERROR LEDS INDICATE SENSOR FAULTS (E.G. A BROKEN WIRE). THE KL3204 VERSION COMBINES FOUR CHANNELS IN ONE HOUSING.

1x KL9020 | TERMINAL BUS EXTENSION, END TERMINAL

THE KL9020 IS ATTACHED TO THE END OF THE BUS TERMINAL BLOCK IN THE SAME WAY AS THE STANDARD TERMINAL KL9010 AND TERMINATES THE TERMINAL BLOCK. THE KL9020 ENABLES THE CONNECTION OF AN ETHERNET CABLE WITH A RJ45 PLUG. THE K-BUS SIGNALS ARE CONVERTED TO RS485. POWER TO THE KL9020 ELECTRONICS IS SUPPLIED VIA THE K-BUS. THE KL9020 FORMS A PROPERLY WORKING UNIT TOGETHER WITH AT LEAST ONE KL9050. APART FROM A SUPPLY VOLTAGE OF 24 V AND THE INSERTION OF THE ETHERNET CABLE, THERE IS NO FURTHER PARAMETERISATION OR CONFIGURATION WORK NECESSARY. THE BUS COUPLER CARRIES OUT ALL DIAGNOSIS AND COMMISSIONING TASKS.
