ABB 07KT92 GJR5250500R0262/07 KT 92 Central Processing Unit

Product Description

The 07KT92 (GJR5250500R0262) is a self-contained central processing unit for ABB’s Procontic and Procontic CS31 distributed control systems, part of the legacy 90 Series architecture. Unlike rack-based PLCs, this module integrates CPU, memory, digital/analog I/O, and communication interfaces into a single compact housing—ideal for standalone or small-scale process control applications.

It executes logic programs stored in 14 KB of FLASH EPROM and supports real-time monitoring and control via its onboard I/O. Communication is handled through dual RS-232 ports (user-configurable for programming or HMI) and an RS-485 system bus for connecting remote I/O or operator panels.

FAQ
Q: Can this CPU be expanded with additional I/O?
A: Yes—via the RS-485 system bus, it supports connection to remote I/O modules within the Procontic CS31 family.

Q: Is programming software still available?
A: ABB’s original PG5 or PCS tools are required. While no longer sold new, licensed copies and migration services are available through authorized support channels.

Q: How does it differ from the 07KT98?
A: The 07KT92 is for Procontic CS31 and includes integrated I/O; the 07KT98 is a CPU-only unit for the Advant OCS platform with no local I/O.
