The basic unit 07 KT 97 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 basic unit.

The basic unit is powered by 24 V DC.

2.1.1.1 Main features

· 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)

· 2 serial interfaces COM1, COM2

– as MODBUS interfaces and

– for programming and test functions

· 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 backup the user program in the RAM

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

– backup 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
