The ABB 07MK92 (GJR5253300R1161) is a freely programmable serial communication module designed for the Advant Controller 31 (AC31) industrial automation system. This module features four serial interfaces enabling flexible connectivity between AC31 controllers and external devices. Two interfaces are configurable as EIA RS-232, RS-422, or RS-485 (COM3, COM4), while two others are dedicated EIA RS-232 interfaces (COM5, COM6). Programming is performed in standard C language using the 907 MK 92 software package, allowing users to define custom communication protocols and transmission types. The module connects to AC31 basic units via a networking interface and exchanges data through connection elements. It includes configurable diagnostic LEDs and operates on 24 V DC power supply, making it suitable for process automation, manufacturing, and energy management applications across harsh industrial environments.
