ABB 07KT97B Programmable Processor Unit

The basic unit 07KT97 R200 is the standard device for all applications. In addition, there are basic units with reduced

performance (e.g. 07KT95 or 07KT96) as well as ones with extended performance (e.g. 07KT97 R260 with

ARCNET connection, 07KT97 R0220 with PROFIBUS connection and 07KT97 R0262 with both ARCNET and

PROFIBUS connection). A comparison table is given on page 3. This document describes the basic unit 07KT97

R200 and then adds the data sheets of the other devices which only show the differences.

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. 07KP90)

·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–tore 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

Features: It can support a variety of analog input signals, such as current, voltage, thermocouple, RTD and so on. 

With high-precision signal acquisition, conversion and transmission capability, it can acquire process parameters in real time and accurately.

Adopting modularized design, easy to install and maintain. With good anti-interference ability, it can adapt to the harsh industrial environment.

07EA90-SI ABB module adopts advanced analog signal processing technology, 

which can quickly and accurately convert analog signals into digital signals and transmit them to the control system through 

the communication interface to realize real-time monitoring and control of industrial processes.
