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 a 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 excels 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
The 07 KT 98 integrates seamlessly with the Advant Controller 31 system via the CS31 system bus interface. 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.
Frequently Asked Questions
Q: Can the analog inputs on the 07 KT 98 be used as digital inputs?
A: Yes, each of the 8 analog input channels can be individually configured as a digital input, providing additional flexibility for mixed-signal applications.
Q: What is the maximum frequency the high-speed counter can handle?
A: The integrated high-speed counter supports counting frequencies up to 50 kHz, configurable in 7 different operating modes.
Q: How do I back up the user program and data?
A: Use the SmartMedia Card (07 MC 90) for storing the operating system, user program, and data. The lithium battery 07 LE 90 backs up RETAIN data and the real-time clock during power-off.
Q: What programming software is required for the 07 KT 98?
A: Use 907 AC 1131 programming software version V 4.1 or later (for ARCNET interface) or V 4.2.1 or later (for PROFIBUS-DP interface).
Q: Can the 07 KT 98 operate as a standalone controller?
A: Yes, the basic unit can work as a stand-alone controller, bus master, or slave in the Advant Controller 31 decentralized automation system.
