ABB 07 KT 98 Advant Controller 31 Basic Unit Terminal Blocks

Product Overview

When your automation system demands reliable control and flexible I/O configuration, the ABB 07 KT 98 Advant Controller 31 Basic Unit delivers a robust solution. This terminal blocks module integrates 24 digital inputs, 16 digital outputs, and 8 configurable digital inputs/outputs, all with LED status indicators. It also features 8 analog inputs and 4 analog outputs, making it a versatile choice for decentralized automation architectures.

Technical Specifications Breakdown

The 07 KT 98 provides an user program memory of 1 MB and user data memory of 1 MB plus 256 kB RETAIN and 128 kB Flash EPROM. Digital inputs are arranged in 3 groups of 8, each electrically isolated, while digital outputs come in 2 groups of 8, also isolated. Analog inputs are individually configurable for 0...10 V, 0...5 V, ±10 V, ±5 V, 0...20 mA, 4...20 mA, Pt100 (2-wire or 3-wire), or as digital inputs. Analog outputs support 0...10 V, 0...20 mA, and 4...20 mA. The unit operates on 24 V DC power and includes a real-time clock and high-speed counter for frequencies up to 50 kHz.

Industry Applications

In manufacturing environments, the 07 KT 98 as a bus master or slave in the Advant Controller 31 system. For example, in a packaging line, its 24 digital inputs can monitor sensor status while the 16 transistor outputs control actuators. The 8 analog inputs allow precise monitoring of temperature via Pt100 sensors, and the 4 analog outputs can regulate variable speed drives. This flexibility reduces the need for additional modules, cutting system cost and complexity.

Installation & Setup Guidance

Mount the 07 KT 98 on a DIN rail or use screws for fixed installation. Connect the 24 V DC power supply to the designated terminals. For digital I/O, use detachable screw-type terminal blocks to simplify wiring. Configure analog input channels via the programming software 907 AC 1131 (version V 4.1 or later) to match your sensor type. The RUN/STOP switch allows easy program execution control during commissioning.

Maintenance & Reliability

Regularly inspect the LED indicators for operating status and error messages. The integrated lithium battery 07 LE 90 backs up RETAIN data and the real-time clock during power loss. Replace the battery according to the manufacturer's schedule to ensure data retention. The SmartMedia Card stores the operating system and user program, providing a convenient way to update firmware or reload programs without a PC.

Compatibility & Integration

It supports serial interfaces COM1 and COM2 as MODBUS interfaces for programming and communication. For expanded connectivity, use couplers like 07 KP 90 (RCOM), 07 KP 93 (2 x MODBUS), or 07 MK 92 (freely programmable). The unit also works with ARCNET or PROFIBUS-DP interfaces when using appropriate programming software versions.
