ABB 07KT94 Advant Basic Controller Unit

The basic unit 07 KT 94 works either as

•bus master in the decentralized automation system Advant Controller 31 or as

•slave (remote processor) in the decentralized automation system Advant Controller 31 or as

•stand-alone central unit.

The device has a 24 V DC power supply voltage.

•24 digital inputs with LED displays

•16 digital transistor outputs with LED displays

•8 digital inputs/outputs with LED displays

•8 individually configurable analog inputs 0...10 V, 0...5 V, ±10 V, ±5 V, 0...20 mA, 4...20 mA, differential inputs, Pt100 (2-wire or 3-wire), the analog inputs are also individually configurable as digital inputs

•4 individually configurable analog outputs ±10 V, 0...20 mA, 4...20 mA

•2 counters for counting frequencies up to 50 kHz, configurable in 7 different operating modes

•1 CS31 system bus interface for system expansion

•1 interface for connecting communication modules (e.g. 07 KP 90)

•Serial interface COM1

– is set as programming interface

– can be set as an ASCII interface for connecting peripheral devices (e.g. MMC devices)

•Serial interface COM2

– as an ASCII interface for connecting peripheral devices (e.g. MMC devices)

–MODBUS master and slave interface

•Real-time clock

•LEDs for displaying operating conditions and error messages

•Detachable screw-type terminal blocks

•Fastening by screws or by snapping the device onto a DIN rail

•The lithium battery 07 LE 90 can be put into the battery compartment in order to

– store and back-up the user program in the RAM

– store and back-up data which is additionally contained in the RAM, e.g. the status of flags

– back-up the time and date (real-time clock)

•RUN/STOP switch for starting and aborting the program execution.

•Extensive diagnosis functions

– Self-diagnosis of the basic unit

– Diagnosis of the CS31 system bus and the connected modules

•Integrated Flash EPROM for storing program and data

•Exchangable Smart Media Card 07 MC 90 for user data or for updating the operating system or PLC program.
