07KT94-S ABB GJR5252100R2201, AC31, Basic Unit

Description:

The basic unit 07KT94-S works either as
· bus master in the decentralized automation system
Advant Controller 31-S or as
· slave (remote processor) in the decentralized automation system Advant Controller 31-S or as
· stand-alone central unit.
The device has a 24 V DC power supply voltage.

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)
· 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.
