BECKHOFF CX9020-0111 BASIC CPU MODULE WITH 3x KL3448,17x KL3204, 1x KL9020 (USED) BECKHOFF CX9020-0111 KL3448 KL3204 KL9020 BASIC CPU MODULE WITH 3x KL3448, 17x KL3204, 1x KL9020 SERIAL NO:132643 HW:3.0 MAC-ID 1: 00-01-05-59-81-3A POWER SUPPLY: 24 VDC, MAX.4A 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.
